1. Carbon Stars in the Large Magellanic Cloud

Carbon stars (C stars) are asymptotic-giant branch stars having masses perhaps a few timesgreater than the Sun which are seen in a relatively short-lived phase of their post-mainsequence evolution. One needs an extremely large parent population of stars e.g., thecontents of an entire galaxy, in order to find a large sample of C stars to study since anindividual star will only spend a brief fraction of its life as a C star. And fortunately, carbonstars are sufficiently luminous to be studied in nearby galaxies.

Edgardo Costa (U. de Chile) and Jay Frogel (Ohio State U.) have recently reported theirresults of an extensive study of the optical and infrared brightnesses and colors for a sampleof 895 carbon stars in the Large Magellanic Cloud from observations made at CTIO overseveral years. The absence of any very bright C stars in this large sample confirms andemphasizes the results from previous work which was based upon samples of smaller size.This deficiency in bright C stars in the LMC translates into an abrupt cutoff in the luminosityfunction at a bolometric absolute magnitude of Mbol = -6. Either a presently unknownphysical mechanism exists which acts to truncate the evolution of asymptotic giants as theyapproach this limiting luminosity or subtleties in their internal evolution prevent the mostmassive stars (which might be expected to become C stars) from actually following thatevolutionary path.

2. The Interstellar Medium of NGC 55

A detailed understanding of how interstellar gas may be cycled through the disk and betweenthe disk and halo of a spiral galaxy is an important factor in eventually understanding theprocesses of galaxy evolution. There is the potential for a complex interaction between starformation, the energy and momentum input from the winds of young stars and supernovae,the ejection of material from the disk into the halo and the return flow of halo gas back intothe disk.

The galaxy NGC 55, a highly inclined disk galaxy and a member of the nearby SculptorGroup of galaxies, is a unique system for studying the disk-halo interface in a late-typegalaxy at high spatial resolution. Using the CTIO 1.5-m telescope Annette Ferguson andRosemary Wyse (Johns Hopkins U.) and Jay Gallagher (U. of Wisconsin) imaged NGC 55 inlight from emission lines of hydrogen, nitrogen, sulfur and oxygen. Because of the proximityof this galaxy, the images have a spatial scale corresponding to 4 pc per pixel.

Page 6: OPTICAL ASTRONOMY OBSERVATORIES Q1...QUARTERLY REPORT OCTOBER -DECEMBER 1996 February 20,1997. I. INTRODUCTION II. SCIENTIFIC HIGHLIGHTS TABLE OF CONTENTS A. Cerro Tololo Inter-AmericanObservatory

A great variety of morphologies are visible in Ferguson, et al.'s images of NGC 55 includingnormal H U regions, loops and plumes protruding typically 1-2 kpc out of the plane of thedisk and diffuse emission throughout the disk and extending out into the halo.

Combining images taken in different atomic transitions, Ferguson, et al. demonstrate thatthere is a continuous trend as one proceeds from regions of high surface brightness to low.The diffuse, low surface brightness gas has oxygen to hydrogen and sulfur to hydrogenemission line ratios that are enhanced by an average factor 2 compared to the bright H IIregions. Both of these results are consistent with the expectations for photoionization of thediffuse medium by a dilute radiation field.

3. Magnetic Activity and Dwarf M Stars

Main sequence stars with masses smaller than about 0.4 of a solar mass make up the class ofdwarf M (dM) stars. Although dM stars are by far the most common and closest stars in thesolar neighborhood, their intrinsic faintness has made dM stars difficult to study in anydetail.

To complete the first detailed spectroscopic survey of the nearby dM stars, Suzanne Hawley(Michigan State U.), John Gizis and Neill Reid (Caltech) used the CTIO 1.5-m to obtainspectra for 317 southern M dwarfs. Combining these observations with data from thenorthern hemisphere, Hawley, et al. use their total sample of 2063 stars to investigate theincidence of magnetic activity in dM stars. As an indicator of chromospheric activity andunderlying magnetic activity, Hawley, et al. choose to use the presence of emission in Ha,i.e., magnetically active stars are the stars that would be classified as dMe.

As had been previously noted by others, Hawley, et al. found the incidence of stellar activityincreased with decreasing temperature (color, spectral type) and mass. By comparing thedMe stars with the dM stars, Hawley, et al. found several empirical differences between thedM and dMe stars in their sample. At spectral type earlier than about M4, dMe stars appearto be 0.5 magnitude brighter and perhaps 0.1 magnitude redder than dM stars of the samespectral type. The dMe stars show variations in the strengths of their Balmer lines ofhydrogen and of the molecular bands of TiO that depend on the level of chromosphericactivity. A kinematic analysis shows that the dMe stars are, as a whole, kinematicallyyounger than the dM stars.

Their relative youth suggests that activity in dM stars, as in the more massive F,G and Kstars, is related to age, possibly via rotation. This is a somewhat surprising result since thesame dynamo mechanism that is presumed to be responsible for producing the activity inmore massive stars should not be operating in these fully convective late M dwarfs.

1. Primordial Helium Revisited

The primordial abundance of helium is a key indicator of physical conditions in the hot BigBang. In the "standard" model of Big Bang nucleosynthesis, the abundances of the lightelements produced near the end of the first three minutes depend on only three physical

Page 7: OPTICAL ASTRONOMY OBSERVATORIES Q1...QUARTERLY REPORT OCTOBER -DECEMBER 1996 February 20,1997. I. INTRODUCTION II. SCIENTIFIC HIGHLIGHTS TABLE OF CONTENTS A. Cerro Tololo Inter-AmericanObservatory

parameters: the number of neutrino species, the neutron lifetime, and the ratio of baryons tophotons. The neutron lifetime has been determined experimentally to be around 890 seconds,and further experiments suggest that there are three neutrino species. The recent diversity ofmeasurements of light element abundances, particularly for deuterium, and theirinconsistency with the simplest picture of Big Bang nucleosynthesis have suggested to somethat there is a crisis in the model. Alternatives have been proposed, based on two neutrinospecies or inhomogeneities in physical conditions. Another possibility, however, is that thederivation of abundances from the difficult spectroscopic measurement needs revision.

Y. Izotov (Ukraine), T.X. Thuan (U. of Viriginia), and the late V. Lipovetsky (Russian 6-mObservatory) report in the January 1997, Astrophysical Journal Supplement, on newobservations and interpretation of the primordial helium abundance. No system of purelyprimordial gas, untouched by stellar processing, has been unambiguously identified. Thetechnique is to measure the helium abundances in a variety of locations with differentabundances of stellar processed material, and extrapolate the observed relationship to thevalue for no stellar nucleosynthesis. The authors used a sample of emission-line galaxiesfrom the Second Byurakan Survey to derive abundances from emission lines arising in starforming regions. The galaxies of the sample typically have very low enrichment fromgenerations of star formation, and provide an excellent basis for extrapolating to primordialvalues.

Izotov and collaborators examined a number of systematic effects that would distort thederived helium abundances from their true values. They found that the strongest effect by farwas in the basic atomic physics, through the difference in the physical coefficients predictingthe relative strengths of helium emission lines and the enhancement of those lines throughelectron collisions. The result is a much weaker dependence of helium abundance on theabundances of stellar synthesized elements such as oxygen and nitrogen. The extrapolation tozero then leads to a higher value of the primordial helium fraction of 0.243 by mass, almost10% higher than some recent determinations. That value is essentially consistent with themeasured neutron lifetime and three neutrino species, and with the baryon to photon ratioderived from the current estimate for primordial lithium and the lower values quoted recentlyfor deuterium. This redetermination of the helium abundance weakens the claim of crisis in

the simple Big Bang model, and raises the interest in resolving the wide variance in thecurrent measurements of deuterium.

Izotov and Lipovetsky were scientific visitors at NOAO Tucson for the analysis that theyreported. The support of their projects has led to a series of significant results, that reinforcethe value of such international collaborations.

2. Rotation, Activity, and Evolution of Hyades M Dwarfs

The distribution of rotational velocities in stars of a nearly coeval cluster is the result of theevolutionary processes at work since formation. There is probably a real spread in initialangular momentum for low-mass stars at birth. The presence of a pre-main sequence diskinhibits the spin-up of a star as it contracts. Those stars with short-lived disks may thereforespin up more and arrive on the main sequence as rapid rotators. Young clusters like thePleiades show a large range in rotational velocities for low-mass stars, consistent with thispicture. Stellar winds carry off angular momentum, with more rapidly rotating stars havinghigher loss rates. The range of rotational velocities therefore decreases with increasing age ofa cluster. The older Hyades cluster shows a limited spread of rotational velocities for solar-

Page 8: OPTICAL ASTRONOMY OBSERVATORIES Q1...QUARTERLY REPORT OCTOBER -DECEMBER 1996 February 20,1997. I. INTRODUCTION II. SCIENTIFIC HIGHLIGHTS TABLE OF CONTENTS A. Cerro Tololo Inter-AmericanObservatory

type G and K stars. It is interesting to ask what happens to the less massive M stars, whichwould have slower angular momentum loss rates and longer times to contraction onto themain sequence.

J. Stauffer (Harvard-Smithsonian), S. Balachandran (U. of Maryland), A. Krishnamurthi,M. Pinsonneault, and D. Terndrup (Ohio State), and R. Stern (Lockheed-Martin) report in the1 February 1997 Astrophysical Journal on their observations of the rotational velocities ofM dwarfs in the Hyades cluster. They used the echelle spectrographs on the Kitt Peak andCTIO 4-m telescopes for 52 late K and M dwarfs. Their upper limit to detectable rotationalvelocity was 6 km/s. They found that lA of their sample had detectable rotational velocitiesabove that limit, with a maximum velocity of about 25 km/s. That maximum corresponds to amain sequence rotational period of only 18 hours, which is quite rapid. They compared thisresult to theoretical models of regulation of angular momentum by a pre-main sequence diskfollowed by spin-up after the disk dissipates. Disk lifetimes typical for the observed rotationlimits of higher mass stars (of about 1 million years) were consistent with the observedmaximum rotation rate for the M dwarfs, but there could be little angular momentum losscaused by stellar winds. Six of the 48 M dwarfs in the sample were double-linedspectroscopic binaries, which is a higher frequency than found in radial velocity surveys inthe field. The frequency of binaries among solar-type stars in the Hyades is also higher thanthat in the field. It is therefore possible that the frequency of such binaries increases with thedensity of the formation region. Curiously, all of the M dwarfs in binaries are slow rotators,which is not consistent with the early dissipation of the pre-main sequence disks anticipatedin close binary systems.

As seen in field stars, the level of activity of the M stars correlates with rotational velocity.That activity is measured in the chromosphere through the strength of hydrogen Balmeralpha emission and in the corona through the strength of X-ray flux. At high rotationalvelocities, the activity level saturates. The authors found some evidence that their randomlychosen sample of stars does not show a distribution of rotational velocities consistent with arandom draw of inclination angles, but may show a two-branch distribution of high and lowrotational velocities at maximum chromospheric and coronal activity. The authors speculateabout two paths to saturated stellar activity. The rapid rotators would originate as weakT-Tauri stars with disks that dissipated early, but the stars then lost some angular momentumfrom winds. The other path originates from classical T Tauri stars with longer-lived disks.These stars may have slower surface rotation from the disk braking, but stronger differentialrotation, leading to saturated activity levels at slower rotational velocities. The binaries withslow rotation are still curiosities in this context, because they uniformly show high levels ofactivity, but again are unlikely to have long-lived disks.

The drive for echelle spectroscopy on large-aperture telescopes becomes strong for thisproblem through the need to extend these faint star studies to yet later spectral types andmore distant clusters.

3. The Continuing Mystery of Warm Gas Layers

Over 90% of the free electrons in the Galaxy come from a warm ionized layer of gas with ascale height above the disk of some 900 parsecs. The existence of this diffuse material, calledthe Reynolds layer, is well established through measurements of hydrogen recombinationradiation and the dispersion of pulsar pulses that have traversed this medium. The mystery is

Page 9: OPTICAL ASTRONOMY OBSERVATORIES Q1...QUARTERLY REPORT OCTOBER -DECEMBER 1996 February 20,1997. I. INTRODUCTION II. SCIENTIFIC HIGHLIGHTS TABLE OF CONTENTS A. Cerro Tololo Inter-AmericanObservatory

the source of ionization of this gas, since the energy requirements are comparable to theenergy released by all Galactic supernovae. A plausible source is the ionizing flux fromO and B stars leaking out of the neutral gas layer in the Galactic plane. Some 15% of thetotal output from the OB stars must escape to higher layers. Determining the physicalconditions in the gas provides diagnostics for the photoionization energy source. The studyof similar warm gas layers in other spiral galaxies should provide further clues to thismystery.

R. J. Rand (U. of New Mexico) reports in the 1 January 1997,Astrophysical Journal on hisobservation of the extended ionizedgas in the edge-onspiral galaxyNGC 891. That galaxy isknown to have a very high rate of star formation in its inner regions, with the X-ray signatureof hot gas ejectedby supernovae extending for kiloparsecs away from its plane. Rand reportson spectra with the Kitt Peak 4-m telescope and RC Spectrograph that were taken at amidplane distance of 5 kiloparsecs from the center of the galaxy, at which conditions aremore quiescent. The spectra recorded three spectral diagnostics to very faint intensities:Hydrogen Balmer alpha, an important helium recombination line (X5876), and the forbiddensingly-ionized nitrogen lines. The line ratios provide the diagnostic of the far and extremeultraviolet energy distribution of the ionizing field. The helium to hydrogen ratio wasmeasured to be 0.034. That value suggests that the gas layer is about 70% ionized and thatthe source of ionization has a significantly stronger extreme ultraviolet to far ultraviolet fluxratio than the source in the Milky Way. The nitrogen to hydrogen ratio peaks at 1.4, whichrequires yet stronger extreme ultraviolet than is permitted by the helium to hydrogen ratio inthe simple photoionization model. The line measurements allow an upper limit to be set onthe temperature of 10-13,000 K depending on location. That value is not yet a sensitiveenough upper limit to resolve the other contradictions, and is considerably above the range of6000-8000 K modeled for the Reynolds layer.

Both the nitrogen and hydrogen were detected to beyond 5 kiloparsecs above the plane. Thedistribution of ionized gas was best fitted by a two-component model, one with a scale heightof around 1 kiloparsec (comparable to that of the Reynolds layer) and the other more diffusecomponent with a scale height of 5-6 kiloparsecs. The gas follows the rotation of the galaxyat small distances above the plane, but shows a decreasing rotation farther from the plane.This effect is qualitatively consistent with models of hot gas being ejected from the plane bysupernova explosions, cooling, and falling back in a galactic fountain. Two physical effectswill force the gas to move radially outward as it is expelled upward: the conservation ofangular momentum as the pull of gravity is weakened by increasing distance, and a gradientin the pressure of gas above the plane. In both cases, the rotation of the gas will decreasewith height. The emission lines may be produced, however, by both warm gas rising and hotgas cooling and falling back, which complicates the picture.

The collection of further information and interpretation is still required, since the elusivesource of ionizing energy has not been unambiguously identified in NGC 891. There is oneimportant caution that we learn about our own Galaxy from studying this neighbor. We mustbe very careful in inferring the location of halo clouds of absorbing gas from their radialvelocities along the lines of sight to stellar and extragalactic probes. The warm gas may notbe rotating on cylinders, and the full complexity of an explosion-induced fountain needs tobe considered.

1. SoHO and the Solar Oscillations Imager Experiment Measure Tiny Changes inthe Shape of the Sun

From the constant environment of space, the SoHO/MDI experiment provides researcherswith the longest series of finely detailed electronic images of the Sun that have ever beenobtained. Because the spacecraft is above the blurring effects of the atmosphere, and with thehelp of sophisticated computer analysis, it is possible to measure exceedingly small changesin the shape of the Sun. These changes are caused by "oscillations" analogous to terrestrialearthquakes. Other ground measurements have observed such oscillations before, but neverhave we been able to actually detect fluctuations in the shape of the Sun because of thesesound waves. The SoHO/MDI experiment is able to detect the edge of the Sun move byabout 10 feet. This sensitivity is equivalent to measuring the size of a quarter placed at theedge of the moon as seen from the surface of the earth.

By observing the Sun as it rotates, the MDI experiment has also revealed that the solarsurface is "corrugated." Its surface is covered with hills and valleys about 5 times thediameter of the earth in lateral size, but with a height of only about Vi kilometer. Althoughthe Sun is gaseous, and has no solid surface, these hills and valleys of hot gas rotate with theaverage 27-day solar surface rotation rate. They are probably caused by a complex magneticfield "network" that threads through the visible surface of the Sun.

2. NSO/SP Completes First Observations with Fast 2K x 2K CCD Camera

A new high-speed, high-dynamic-range CCD camera has been developed in collaboration withXedar Inc. (Boulder, Colorado). This instrument was developed for the RISE/PSPT project andused a new Thomson 2K x 2K CCD array. One 2K x 2K camera has been purchased forgeneral use at NSO/SP. We plan to purchase a second such general-use 2K x 2K camera unit asfunds become available.

The first two RISE/PSPT camera units have been received at NSO/SP and have passedpreliminary tests. A detailed performance characterization is currently being performed atNSO/SP. The 2K x 2K cameras have a linear well depth of about 200,000 electrons, with a readnoise of about 34 electrons, when operated at a read rate of 8 million pixels/sec. The cameraelectronics allow a second fiber optic connection to a Sun/SPARC controller that will allow atotal readout rate of 16 Mpix/s. The cameras can also be used in a IK x IK mode using on-chipbinning. The data can be stored to exabyte tape or hard disk. A fast, high-capacity DLT tapedrive will also be available for the 2K x 2K system. The first of these cameras is available on ashared risk basis for observations during the spring 1997 quarter at NSO/SP. The first observingrun, which used the NSO/SP 2K x 2K camera behind the UBF to study acoustic flux events inthe solar photosphere, was successfully completed in January 1997.

D. US Gemini Program

During this quarter, important milestones were passed for two of the first generation Geminiinstruments, the Near-IR spectrograph and the High-Resolution Optical Spectrograph. The Near-IR spectrograph is being designed and fabricated by the NOAO Instrument Project Group. Inmid-October, this instrument passed its preliminary design review. Detailed design work is

Page 11: OPTICAL ASTRONOMY OBSERVATORIES Q1...QUARTERLY REPORT OCTOBER -DECEMBER 1996 February 20,1997. I. INTRODUCTION II. SCIENTIFIC HIGHLIGHTS TABLE OF CONTENTS A. Cerro Tololo Inter-AmericanObservatory

proceeding towards a critical design review to be held in October 1997. At a much morepreliminary stage, the High-Resolution Optical Spectrograph completed its conceptual designreview in London, England in November 1996. It is being designed by a group at UniversityCollege, London. The USGP was represented by Sam Barden, who also sat on the reviewcommittee.

Scientific discussions, both national and international, on the operations strategy for the Geminitelescopes took place during this quarter. A meeting of the Gemini Operations Science WorkingGroup refined the processes that are being defined for the data flow through the Geminifacilities, with emphasis on the implementation of queue scheduling and the proposal process. Ithas been decided that the national project offices will have much of the responsibility forcommunity interaction in the operations phase of Gemini. This will include such activities assupporting the preparation of observing proposals, soliciting and evaluating those proposals, andsupporting data reduction and archive access.

Operations were also a major focus of both the US Gemini Science Advisory CommitteeMeeting, and the Gemini Science Committee Meeting, both held in Tucson. In addition toreviewing strategies for operations, these groups developed the plan for the Gemini ongoinginstrumentation program. Preliminary discussions (starting with a US workshop that the USGPheld in August) had led to a "strawman" instrument complement including upgrades, newinstruments, and instruments to be shared with the national observatories of the partner countries.This US perspective was merged with similar plans from the other partners and discussed by boththe US Gemini SAC, and the GSC. The scientific basis for this plan was to be the subject of aninternational workshop in January 1997 with international participation.

The USGP also participated in the meeting of the KPNO/CTIO joint users' committee inDecember. It has been recognized that there must be increasing crosstalk between USGP and theother divisions in order to develop common solutions to common problems. This point was madeby the US Gemini SAC and the joint users' committee, both of which desire to merge parts oftheir activities and discussions.

Fire Alarm System:

The antiquated fire alarm system in the Tucson facility main Computer Room was replaced with a state-of-the-art system.

Fire Prevention - Brush/Tree Removal:

An extensive brush-tree removal effort was carried out at KPNO. This was a much needed preventivemeasure to reduce the risk of a wildfire destroying major facilities. The majority of the work was done bythe fire crews from the BIA/Tohono O'Odham Wildfire Management at no cost to NOAO. KPNOassisted with loading and hauling off the cuttings.

In conjunction with this a document titled "Wildfire at Kitt Peak National Observatory" was producedfor information and training purposes. It describes in detail what KPNO's and the responding agencies'role would be in the event of a wildfire.

Department of Labor/BLS Statistics Survey:

A mandatory survey of the 1995 occupational injuries for the KPNO and Tucson Sites was prepared andsent to the Arizona Industrial Commission.
