II. SCIENTIFIC HIGHLIGHTS
A. Cerro Tololo Inter-American Observatory
1. Recent Developments About CN and CH Inhomogeneities in Globular Clusters
A previous CTIO scientific highlight report described how observers at CTIO and KPNO in the 1970s found that giantstars withsimilarluminosities andtemperatures in givenglobularclusters showed CN and CH band strengths with unexpected large differences. In addition, evidence had been found that the (C+N)/H abundance ratio was constant among the stars in a given cluster even though the same stars showed a C, N anti-correlation. This suggested that material processed in the CNO thermonuclear cycle was present in the outer layers of the stars. Unless a star was formed from interstellar material with CN and CH inhomogeneities, the observations suggested that in a given star material from its deep interior had been mixed into the outer envelope. Puzzling aspects of these explanations were that the distribution of CN band strengths could be bimodal and that, as shown in 1991 by CTIO observers M.M. Briley (U. of Texas), J.E. Hesser (Dominion Astrophysical Obs.), and R.A. Bell (U. of Maryland), the CN bimodality was also found among main sequence stars in the globular cluster 47 Tucanae. In theory, no mixing should occur between the outer envelopes and deep interiors in such stars.
Additional evidence that the inhomogeneities were related to the CNO cycle was found in 1989 by CTIO observers J.E. Brown and G. Wallerstein (U. of Washington), who determined the isotopic 12C/13C abundance ratio from the strength of 13CN and 12CN bands for a number of giants in several clusters. In the CNO cycle, 12C nuclei are convened to 13C with the net effect oflowering the 12C/13C ratio from about 90 to an equilibrium value near 3. This ratio is therefore a sensitive indicator of CNO cycle processed material. In the Brown-Wallerstein study, values in the range 3-8 were found for CN strong stars, the only ones for which the ratio could be evaluated from 13CN and 12CN strengths.
The 12C/13C ratio has recently been determined for CN-strong and CN-weak giants by CTIO staff astronomer N.B. Suntzeff in collaboration with V.V. Smith (U. of Texas). Using the infrared spectrometer with the CTIO 4-m telescope,Suntzeffand Smith determined the strength of the 2.3u.m CO bands in forty- five stars of the clusters M4 and NGC 6752. A wavelength difference between 13CO and 12CO bands makes possible evaluation ofthe desired ratio. The results show that 12C/13C isclose tothe low equilibrium value regardless of the strength of CN bands. Suntzeff and Smith also confirmed earlier findings that in a given cluster the abundance of carbon decreases as a star ascends the giant branch. This decrease suggests an evolutionary effect, which by itself, however, does not explain the low 12C/13C ratios. Their study therefore included observations of possible CN and CH inhomogeneities in stars well below the turn off in the color-magnitude diagram, thus extending to fainter stars than did the previous study by Briley, Hesser, and Bell. CN and CH variations were found in the observed faint unevolved subdwarf stars. In a study by KPNO observers C. Sneden, C.A. Pilachowski, and D.A. VandenBerg, 12C/13C lower limits appreciably above equilibrium value were found in two population II subdwarfs; this result indicates that no mixing between the outer envelopes and deep interior occurs in these stars, as expected from theory. This finding and an observed correlation of CN strength with Na and Al, elements that may be produced in the evolution of luminous giants with masses appreciably larger than those of globular cluster giants, suggest that at least part of the material now present in the outer envelopes of globular cluster stars has been processed by CNO cycles operating in an earlier generation of massive cluster stars.
2. The Evolution of Barium and Subgiant CH Stars
In the early years of spectral classification, a group of red stars was found to show spectra with strong Q molecular bands. Succeeding studies showed that among these "carbon" stars, one could find diverse species with difficult to explain spectral features. Understanding the origin of these species has long been a challenging problem. In particular, in 1941 a group of five carbon stars was found to show CH and CN molecular bands in their spectra. Curiously, these five stars included the three carbon stars with the highest known radial velocities. Such high velocities are usually found among members of the galactic stellar halo population. Later studies showed that CH stars included a subgroup with spectra showing unusually strong Ba II A.4554 lines, and that many CH stars did not have the bright luminosity of classical carbon stars. The carbon spectral features could be understood as resulting from CNO cycle reactions in the stars' cores and outward convective transport of carbon. The presence of barium indicated that some other thermonuclear reaction was occurring, This was later identified as the s-process or slow-neutron capture by heavy "seed" nuclei, which could produce barium and other relatively heavy elements such as strontium and technetium. The discovery in 1952 in S stars of 98Tc, an isotope with a half-life of about4 x 10* years, confirmed that s-process material could be transported outward in reasonably short times. The classical luminous carbon and S-stars are believed, according to current theory, to represent evolutionary stages as stars, with masses in a certain range, evolve along the asymptotic giant branch (AGB) and undergo periodic dredging episodes that transport nuclear-processed material to the stars' outer envelopes.
A serious problem, however, was that the lower luminosity CH stars could not be undergoing AGB evolution. A possible explanation ofwhy such stars have carbon-related spectral features was the discovery by Canadian astronomer R.D. McClure, that many CH stars and barium stars are members of binary systems. This suggested an evolutionary relationship between the low luminosity CH stars and at least some barium stars. Presumably the carbon producing AGB mechanism had taken place in stars that had already evolved and transferred part of their mass to surviving lower luminosity companions. According to this hypothesis, main sequence and subgiant CH and barium stars could exist This was indeed found to be the case in 1974 when Louisiana State University astronomer H.E. Bond used the University of Michigan Curtis Schmidt telescope at CTIO to identify a group of CH stars with luminosities appreciably fainter than those of AGB stars. Bond's designation for this group was "subgiant CH stars." Several such stars showed the Ba II A.4554 line.
Recently, R.E. Luck (Case Western Reserve U.) and H.E. Bond (now at Space Telescope Science Institute) have completed the analysis of echelle spectrograms obtained with the 4-m telescopes at CTIO and at KPNO. The observations included 15 stars formerly classified as subgiant CH stars and five barium stars. The analyses show that the CH stars have atmospheric parameters typical of F and G type main sequence stars, and that the barium stars have atmospheres typical of G and K giant stars. The abundance of s-process elements was found to be practically identical for both the CH and barium stars. The Luck and Bond study strongly suggests that a CH star can indeed be created when an AGB star in a binary contaminates, as it evolves, a main sequence companion with carbon and s-process elements. Later, the main sequence component of the binary system can evolve into a red giant star which then appears to be a barium star.

1. Observational Limits to the Axion Mass
A puzzle for many years in theoretical physics has been the robust nature of the combined charge and parity (CP) invariance in strong interactions. Within the context of quantum chromodynamics, CP violation should occur in strong interactions at a much higher level-by a factor of 109--than is seen experimentally. A way out of this dilemma is to introduce a new global symmetry into the theory which, when broken, produces a particle of non-zero mass, the axion. Experimental detection of this particle would be strong evidence in support of this extension of quantum chromodynamics, but efforts to do this have been unfruitful. Shortly after the introduction of inflationary cosmological models, another role for the axion was found, namely that of a non-baryonic dark matter candidate. Axion masses are limited to two ranges: 1CT6 eV - 10"3 eV and 3 eV - 8 eV, and particles in this mass range are particularly attractive candidates for closing the Universe in conventional cosmology. An axion can decay into two photons, either through axion-pion mixing or through interaction with an electromagnetic field, and this decay provides a possible mechanism for their detection. The higher mass range axions produce a line at optical wavelengths when they decay and, because these particles are non-relativistic, they will be most concentrated where baryons are most concentrated (i.e., in clusters of galaxies).
An observational program to search for the light of axion decay has now been carried out. M.T. Ressell (U. of Chicago) has used the KPNO 2.1-m telescope with the GoldCam spectrograph to observe the clusters A1413, A2218, and A2256 for evidence of diffuse background light that would be expected from the decay of axions in the high mass range if they were present in cosmologically significant numbers. The observations yielded no evidence for the expected line emission from the particle decay. Therefore, the measurements effectively rule out massive axions as non-baryonic cold dark matter candidates. These results provide an important constraint on cold dark matter theories and serve to reduce the allowed parameter space for this troubled cosmology.
2. Clues to Galaxy Formation: Are Neighbors Needed?
In the last fifteen years, observations have provided dramatic evidence for a dynamic and continually evolving Universe-a picture which is radically different from the one that had become established over the previous centuries. Although evidence remains that the Universe itself was created instantaneously, its condensed contents were almost surely not. Galaxies seem now to be coming into being at all epochs, and periods of strong galactic evolution are seen throughout the age of the Universe. The process of galaxy formation itself is still shrouded in mystery, but if in fact galaxies are forming at the present epoch then there is hope that the phenomenon may be observed nearby. Possible evidence for protogalaxies has recently been found, first by Giovanelli and Haynes, who discovered a large and nearby cloud of neutral hydrogen surrounding a small dwarf galaxy, and then by Morris et al., who found several low redshift Lyman-a absorption systems along the line of sight to 3C 273. Are these clouds really protogalaxies which will exhibit soon bursts of star formation? Or are they "leftovers" from galaxies already formed, wisps of hydrogen that will eventually dissipate back into the IGM? This is a crucial issue in our understanding of galaxy formation. If the first case is true, galaxies can form at all epochs down to the present. We are faced then with solving the difficult problem of how to make a gravitationally bound cloud, which must happen at fairly early epochs, and yet keep it from condensing into stars for billions of years. If the second case is true, the disposition of this debris around galaxies is more easily understood. Thus, it is important to take a census of the galaxy population in the neighborhoods around these clouds. This has been done by J. Salzer (Wesleyan U.) using the Arecibo Observatory and the KPNO 2.1-m telescope. With these telescopes, Salzer has obtained redshifts for 51 galaxies near the H I and Lyman-a clouds to determine if these clouds are associated with galaxies already formed. Only one of the Lyman-a clouds can be directly associated with a specific galaxy; the separation, even in this instance, is rather large-180 kpc. However, all the clouds do appear to lie within or near the large scale structure defined by the galaxies. There is no obvious tendency for the clouds to be found in voids. What does this tantalizing result imply? Probably that our ideas about galaxy formation are still much too naive, and that the two questions posed above are too simple. It may be that the broad, flat potential well, formed by the very large scale structure, is sufficient to cradle the protogalactic clouds for a long period, and that star formation is triggered by a local event such as the close passage of another galaxy. These observations not only illustrate again the over-simplification of current models of galaxy formation, but also point out the need for further careful observations at higher redshifts.

1. IR Atlas of a Sunspot Umbra
On 25 July 1991 a large regular sunspot was noted at disk center at a time when the sky was clear, the seeing good, and William Livingston was scheduled on the FTS with the CaF (IR) beamsplitter in place. After locating the darkest position in the umbra, two sets of observations were taken at different air masses. Lloyd Wallace (KPNO) has now prepared an atlas from these spectra that is free of telluric lines by a point-by-point extrapolation to zero air mass. He has also attempted line identifications where possible. Because this was an exceptionally dark spot, the spectrum is noticeably different than, say, the atlas of Don Hall (D.N.B. Hall, 1974, "An Atlas of Infrared Spectra of the Solar Photosphere and of Sunspot Umbrae, in the Spectral Intervals 4040 cm"1 - 5095 cm"1, 5550 cm'1 - 6700 cm"1, 7400 cm"1 - 8790 cm'1," Kitt Peak National Observatory, Tucson, AZ). The measured field strength is about 3500 Gauss. Livingston and Wallace estimate the equivalent spectral type as Ml (whereas most umbrae are early K). Solar CO, OH, and H2 dominate with hundreds of lines present. Livingston and Wallace plan to publish this atlas as an NSO Technical Report.
2. Propagation of High-frequency Waves in the Solar Atmosphere
Stephen Keil (USAF, Phillips Lab, NSO/SP) and Kevin Reardon (an REU student from Williams College at NSO) have completed work on a set of data that was used to measure properties of high-frequency waves in the solar atmosphere. The goals of the project were to extend observations of propagating waves to frequencies above 10 mHz using image stabilization and to investigate the effects of magnetic structures on the propagation. A spot tracker and agile mirror were used to remove image motion by locking onto a small pore before feeding a high resolution solar image into the echelle spectrograph of the NSO/SP Vacuum Tower Telescope (VTT). They found that the propagation of the waves is very dependent on spatial position in the atmosphere. At many spatial points, close enough to the small pore to be well tracked (about 10"), phasedifferences between velocity fluctuations at two heights in the solar atmosphere showed upward propagating characteristics out to 30-40 mHz. The transition from trapped waves to running waves occurred typically around 5-6 mHz as expected for the quiet sun. Near the boundary of the pore, the transition frequency moved out to about 20 mHz and downward propagation was observed. Inside the pore, the phase differencesappeared to show upward propagationout to about 12mHz and then clustered around zero. Energy being carried by the waves appears to decrease from about 5 x 105 ergs/cm/sec at a height of 280 km to 2 x 10s ergs/cm/sec at a height of 580 km in the atmosphere. These observations indicate that these waves probably play an important role in the heating of the upper photosphere and temperature minimum region. Magnetic flux tubes decrease the upward propagation in the observed waves. A poster paper on these results was presented at the American Astronomical Society meeting in Atlanta, and a manuscript is in preparation. Further observations are needed to determine whether the flux being carried in the observed acoustic modes is converted into an MHD mode at the pore. Observations designed to test this idea were started in late December 1991 at the NSO/SP VTT.
3. Liquid Crystal Polarimeter for Fast Zeeman Imaging at NSO/SP
A liquid crystal polarimeter will be assembled in early 1992 and tested at the NSO/SP Vacuum Tower Telescope by Larry November as part of the Air Force-funded Liquid Crystal Filter (LCF) project. A sandwich containing both fast, two-state "Ferro-electric" liquid crystals from DisplayTech and slower, variable "Nematic" liquid crystals from Meadowlark Optics provides rapid modulation of the polarization state entering the Universal Birefringent Filter (UBF). A sandwich at the exit of the UBF gives concurrent spectral modulation in two simultaneous imaging CCD channels. A modulator control system designed and built by Larry Wilkins permits cycling of the liquid crystal elements synchronously to give multiple configurations selectable by computer control.
Bench tests demonstrate that the "Ferro-electric" liquid crystals can be cycled as fast as 10 kHz. This rate determines the time delay of 50 microseconds between the sampling of each polarization/spectral position that defines a polarization/spectral state. The basic polarization measure will be essentially unaffected by the atmospheric seeing variation. Eight polarization/spectral states form a complete sample, which is obtained in eight separate integrations. Presently the measurement cycle is limited in time by the CCD readout, which in the current test will be about 1 second. Second-order errors, which arise due to the relatively slow cycling between the individual polarization/spectral states, will be removed using image "destretching." A future upgrade will operate the system at video rates to give one polarization/spectral state in each 1/30 second and incorporate a feature of the modulator control system that permits synchronous time coding of multiple video channels.
The liquid crystal spatial uniformity and field have been measured and found to be adequate for the application, given regular passive calibration for drift in retardation. The set of eight polarization/spectral states, which contains sixteen nonindependent parameters, gives both information about the sun as well as the observing system and makes it possible to calibrate both the liquid crystal polarimeter as well as the telescope. Even though the VTT entrance window has less than 10'3 deviation from spatial uniformity over its aperture, a net strong polarization effect does occur due to numerous oblique reflections in the optical train. Spatially averaged correlations between the polarization/spectral states provide a complete determination of a Mueller matrix for the telescope. Once corrected, the set of eight polarization/spectral states then provides the vector magnetic flux, velocity, average line width, and depth by linear relationships given by the weak field approximation for a Zeeman-split spectral line. Additional physical information, the field filling factor, is available by comparing observations from similarly formed spectral lines having differing magnetic sensitivities.
The system should be well-suited for fast Zeeman imaging used in conjunction with the relatively broad 1/4 A transmission of the fully tunable UBF and the 76-cm aperture VTT. Thus, the system is designed to study the vector magnetic field with high spatial and temporal resolution at the sacrifice of spectral information. The system should be adaptable to studies of the physics of magnetic structure, fine features and field morphology, and their evolution.
4, X-ray Bright Points Observed Simultaneously with SXT and with the NSO/Kitt Peak 512-channel Magnetograph
With the successful launch of Solar-A, now known as Yohkoh, a study has been initiated to study X-ray bright points (BP). Current participants in this investigation, the Soft X-ray Telescope (SXT) Science Team, are Karen Harvey (SPRC/NSO/T). Keith Strong (Lockheed), Nariaki Nitta (Lockheed), Saku Tsuneta (U. Tokyo), and Toshifumi Shimizu (ISAS).
Our current knowledge of BPs originates from Skylab x-ray images and a few sounding rockets. The SXT, with a lower scatter and higher dynamic range, should be capable of studying BPs in better detail, at a higher cadence, and over a longer period than has been possible to date. It is the first opportunity to obtain ground-based, time-sequence data simultaneously with a time-series of x-ray images and should result in significant progress in understanding BPs and their relation to the magnetic field and other phenomena.
Our initial study of BPs is the investigation of some of their basic properties. This is the first in a series of observational steps that we feel are necessary to improve our understanding of BPs. We plan to measure (1) their spatial distribution and relation to magnetic fields, and (2) their size and lifetime distribution. An important goal will be the determination of an objective definition of a BP. The following will be measured: (1) location and position relative to other coronal and photospheric features, (2) size, temperature, and emission measure, and (3) lifetime - - using extended sequences of SXT images.
The first ever simultaneous observations of BPs and the underlying photospheric magnetic field were acquired on 21 November 1991 using the SXT and the 512-channel magnetograph at NSO/Kitt Peak. These data are being compared to determine how these small-scale x-ray emission structures are associated with the evolution of the magnetic field. A program has been developed by K. Strong and K. Harvey to isolate and follow the light curves of BPs. It has been tested on two of the several bright points observed on 21-22 November 1991; one of the bright points was associated with an emerging magnetic bipole and the other a site of canceling opposite polarities. The light curves of each of the BPs are substantially different. More observations will be obtained to determine if this difference is significant. III. PERSONNEL AND BUDGET STATISTICS, NOAO
