Physics of Evolved Stars: A Conference Dedicated to the Memory of Olivier Chesneau, Nice, Fransa, 08 Haziran 2015, ss.345-346
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.
