Tracking the evolution of lithium in giants using asteroseismology: Super-Li-rich stars are almost exclusively young red-clump stars
Raghubar Singh, Bacham E. Reddy, Simon W. Campbell +2
We report novel observational evidence on the evolutionary status of lithium-rich giant stars by combining asteroseismic and lithium abundance data. Comparing observations and mode…
Concerning Li-rich status of KIC~9821622: A Kepler field RGB star reported as Li-rich Giant
Raghubar Singh, Bharat Kumar Yerra, Bacham E. Reddy +1
Given the implications for the origin of Li enhancement in red giants we have reviewed Li-rich classification of KIC~9821622, the only bonafide RGB giant with He inert-core till da…
Survey of Li-rich giants among Kepler and LAMOST fields: Determination of Li-rich giants Evolutionary Phase
Raghubar Singh, Bacham E. Reddy, Yerra Bharat Kumar +1
In this letter, we report the discovery of 24 new super Li-rich (A(Li) 3.2) giants of He-core burning phase at red clump region. Results are based on systematic search of a l…
Spectroscopic study of two new super Li rich red clump K giants
Raghubar Singh, Bacham E. Reddy, Yerra Bharat Kumar
In this paper, we report the discovery of two new super Li-rich K giants: HD~24960 and TYC~1751-1713-1. Based on high resolution () spectroscopy, we have derived L…
Two new Super Li-rich core He-burning giants: A new twist to the long tale of Li enhancement in K giants
Yerra Bharat Kumar, Raghubar Singh, B. Eswar Reddy +1
In this paper we report two new super Li-rich K giants: KIC 2305930 and KIC 12645107 with Li abundances exceeding that of ISM (A(Li) 3.2 dex). Importantly, both the giants h…
