Abundances of Baade's Window Giants from Keck/HIRES Spectra: I. Stellar Parameters and [Fe/H] Values

Jon. P. Fulbright, Andrew McWilliam, R. Michael Rich

We present the first results of a new abundance survey of the Milky Way bulge based on Keck/HIRES spectra of 27 K-giants in the Baade's Window (, ) field. The spectr…

Dynamics and Stellar Content of the Giant Southern Stream in M31. II. Interpretation

Andreea S. Font, Kathryn V. Johnston, Puragra Guhathakurta +2

We examine the nature of the progenitor of the giant stellar stream in M31 using as constraints new radial velocity measurements of stream red giant stars (presented in the compani…

Cool White Dwarfs Revisited -- New Spectroscopy and Photometry

Samir Salim, R. Michael Rich, Brad M. Hansen +3

In this paper we present new and improved data on 38 cool white dwarfs identified by Oppenheimer et al. 2001 (OHDHS) as candidate dark halo objects. Using the high-res spectra obta…

Evidence for a Significant Intermediate-Age Population in the M31 Halo from Main Sequence Photometry

Thomas M. Brown, Henry C. Ferguson, Ed Smith +5

We present a color-magnitude diagram (CMD) for a minor-axis field in the halo of the Andromeda galaxy (M31), 51 arcmin (11 kpc) from the nucleus. These observations, taken with the…
