A Determination of the Thick Disk Chemical Abundance Distribution: Implications for Galaxy Evolution
Abstract
We present a determination of the thick disk iron abundance distribution obtained from an in situ sample of F/G stars. These stars are faint, $15 \simlt V \simlt 18$, selected on the basis of color, being a subset of the larger survey of Gilmore and Wyse designed to determine the properties of the stellar populations several kiloparsecs from the Sun. The fields studied in the present paper probe the iron abundance distribution of the stellar populations of the Galaxy at 500--3000pc above the plane, at the solar Galactocentric distance.
