Testing Metal Poor Stellar Models and Isochrones with HST Parallaxes of Metal Poor Stars
B. Chaboyer, B. E. McArthur, E. O'Malley +7
Hubble Space Telescope (HST) fine guidance sensor observations were used to obtain parallaxes of eight metal-poor ([Fe/H] < -1.4) stars. The parallaxes of these stars determined by…
Global Properties of M31's Stellar Halo from the SPLASH Survey: II. Metallicity Profile
Karoline M. Gilbert, Jason S. Kalirai, Puragra Guhathakurta +9
We present the metallicity distribution of red giant branch (RGB) stars in M31's stellar halo, derived from photometric metallicity estimates for over 1500 spectroscopically confir…
Global Properties of M31's Stellar Halo from the SPLASH Survey. I. Surface Brightness Profile
Karoline M. Gilbert, Puragra Guhathakurta, Rachael L. Beaton +10
We present the surface brightness profile of M31's stellar halo out to a projected radius of 175 kpc. The surface brightness estimates are based on confirmed samples of M31 red gia…
A 2MASS All-Sky View of the Sagittarius Dwarf Galaxy: VII. Kinematics of the Main Body of the Sagittarius dSph
Peter M. Frinchaboy, Steven R. Majewski, Ricardo R. Munoz +5
We have assembled a large-area spectroscopic survey of giant stars in the Sagittarius (Sgr) dwarf galaxy core. Using medium resolution (R ~15,000), multifiber spectroscopy we have…
Exploring Halo Substructure with Giant Stars: Substructure in the Local Halo as Seen in the Grid Giant Star Survey Including Extended Tidal Debris from Omega Centauri
Steven R. Majewski, David L. Nidever, Verne V. Smith +5
We present the latitude-normalized radial velocity (vb) distribution of 3318 subsolar metallicity, V<13.5 stars from the Grid Giant Star Survey (GGSS) in Southern Hemisphere fields…
Identifying Contributions to the Stellar Halo from Accreted, Kicked-Out, and In Situ Populations
Allyson A. Sheffield, Steven R. Majewski, Kathryn V. Johnston +10
[Abridged] We present a medium-resolution spectroscopic survey of late-type giant stars at mid-Galactic latitudes of (30), designed to probe the properties…
