Seminar
Over abundances of Lithium in stars of red giant branch: Current Status
Eswar Reddy
Abstract
Abstract: A small group of giants on RGB show anomalously large amounts of Li in their
photospheres. In some cases, Li abundance exceeds stars' natal clouds (A(Li) = 3.2~dex)
suggesting addition of fresh Li during stars' evolution on RGB. However, the mechanism
that is responsible for such large enhancement is not understood. In this talk, I will describe
observational results till date, possible scenarios for its origin and implications to Galactic Li
enrichment.
