Hi-Res Spectroscopy of a Volume-Limited Hipparcos Sample within 100 parsec
P. L. Lim, J. A. Holtzman, V. V. Smith +1
We obtain high-resolution echelle spectra of evolved Hipparcos stars within 100 parsec for detailed abundance analysis. We are particularly interested in subgiants because their ag…
Photometric observations of Grid Giant Star Survey candidates
D. Bizyaev, V. V. Smith, J. Arenas +1
We compare variability of radial velocity (RV) and brightness for a sample of red giants which were selected as candidates for the Grid Giant Star Survey (GGSS). The purpose of the…
Chemical Evolution in Omega Centauri
Verne V. Smith
The globular cluster Omega Centauri displays evidence of a complex star formation history and peculiar internal chemical evolution, setting it apart from essentially all other glob…
Isotopic lithium abundances in five metal-poor disk stars
P. E. Nissen, D. L. Lambert, F. Primas +1
High resolution (R=110000), very high S/N spectra, centered on the 6707.8A LiI line have been obtained with the ESO Coude Echelle Spectrometer for five, metal-poor (-0.8 < [Fe/H] <…
Properties of a Proper-Motion Selected Sample of Giants in the Small Magellanic Cloud near NGC 121
Nicholas B. Suntzeff, Alistair R. Walker, Verne V. Smith +3
We present both low and high-dispersion abundance analyses of giants drawn from the zero proper motion sample near NGC 121. For the sample of 35 stars, the mean metallicity of the…
