Search for Lithium-Rich Stars Among G-K Giants with IR-excess

Jasniewicz, G; Parthasarathy, M; de Laverny, P; Thevenin, F; Mauron, N; Chadid, M (International Astronomical Union, 2000)

We report here new results about a search for Li- rich stars among 52 G-K giant stars which are known to have near IR excess. Eleven giants have been found to have loge (Li)≥ 1.0. Five are new Li-rich stars. We suspect ...
Weak G-band stars on the H-R diagram: clues to the origin of the Li anomaly

Palacios, A; Parthasarathy, M; Bharat Kumar, Y; Jasniewicz, G (EDP Sciences, 2012-02)

Aims. Weak G-band (WGB) stars are a rare class of cool luminous stars that present a strong depletion in carbon, but also lithium abundance anomalies that have been little explored in the literature since the first discovery ...
