Li-enrichment in red clump giants: Clues for past binary interaction or merger events
Raghubar Singh, Bacham E. Reddy, Anohita Mallick +1
To understand the underlying mechanisms for high lithium abundances among core He-burning or red clump (RC) giants, we analyzed a sample of 5227 RC giants of mass M 2~M$_{\o…

High Lithium Abundance Connection with the Chromospheric Helium in Red Giants: Spectroscopic and Asteroseismic analyses
Anohita Mallick, Christopher Sneden, Bacham E. Reddy +1
We present a study of correlations between high Li abundances and strong chromospheric He I 10830 Å absorption line strengths in Kepler field giant stars. Our sample includes 84 gi…
