Abstract

In this study we conducted the first large-sample red horizontal branch field star survey in the Milky Way. We carried out a detailed high-resolution spectroscopic abundance analysis of the RHB candidates. We also derived C-12/C-13 isotopic ratios, important indicators of stellar evolution, by using the CN features mainly located around the 8004 angstrom.
