Abstract

Abstract We report the results of a search for candidate Li-rich giants among 569,738 stars of the SDSS DR10 data set. With small variations, our approach is based on that taken in an earlier search for extremely metal-poor/carbon-enhanced metal-poor stars and uses the same data set. As part of our investigation, we demonstrate a method for separating post-main-sequence and main-sequence stars cooler than T eff ≈ 5800 K using our feature strength measures of the Sr ii 4078, Fe i 4072, and Ca i 4227 lines. By taking carefully selected cuts in a multi-dimensional phase space, we isolate a sample of potential Li-rich giant stars. From these, using detailed comparison with dwarf and giant MILES stars, and our own individual spectral classifications, we identify a set of high likelihood candidate Li-rich giant stars. We offer these for further study to promote an understanding of these enigmatic objects.
