Abstract

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 log ∊(Li) ≥ 1.0. Five are new Li-rich stars. We suspect circumstellar shells around one of them, HD 219025. There is no clear correlation between Li-richness and rotation, or with binarity.
