On the link between rotation and lithium depletion in subgiant stars.

DE MEDEIROS J.R., DO NASCIMENTO J.D.Jr and MAYOR M.

Abstract (from CDS):

We present projected rotational velocity Vsini for 65 F, G and K subgiant stars. In this work we study the link between rotation and Lithium abundance in such class of luminosity. In particular, we look for possible effects of rotational braking on the Lithium depletion. We show that a sharp decrease in Lithium abundances parallels the rotational discontinuity, located at F8IV, in all its aspects. We have found some dependence of Lithium abundance upon rotation for single subgiants, but there is no evident correlation between Lithium abundance and rotational velocity for binary subgiant stars.
