Metal-poor stars towards the Galactic bulge - a population potpourri
Andreas Koch, Andrew McWilliam, George W. Preston +1
We present a comprehensive chemical abundance analysis of five red giants and two horizontal branch (HB) stars towards the southern Galactic bulge, at (l,b)(0,-11$^…
The Absolute Magnitude of RRc Variables From Statistical Parallax
Juna A. Kollmeier, Dorota M. Szczygiel, Christopher R. Burns +12
We present the first definitive measurement of the absolute magnitude of RR Lyrae c-type variable stars (RRc) determined purely from statistical parallax. We use a sample of 247 RR…
Characterizing the Chemistry of the Milky Way Stellar Halo: Detailed Chemical Analysis of a Metal-Poor Stellar Stream
Ian U. Roederer, Christopher Sneden, Ian B. Thompson +2
We present the results of a detailed abundance analysis of one of the confirmed building blocks of the Milky Way stellar halo, a kinematically-coherent metal-poor stellar stream. W…
Spectroscopic Confirmation of the Pisces Overdensity
Juna A. Kollmeier, Andrew Gould, Stephen Shectman +6
We present spectroscopic confirmation of the "Pisces Overdensity", also known as "Structure J", a photometric overdensity of RR Lyrae stars discovered by the Sloan Digital Sky Surv…
