The hot side of the lithium dip - LiBeB abundances beyond the main sequence

Astrophysics 2007-05-23 v1

Abstract

We extend to the case of A and early-F type stars our study of the transport of matter and angular momentum by wind-driven meridional circulation and shear turbulence. We show that our fully consistent treatment of the same hydrodynamical processes which can account for C and N anomalies in B type stars (Talon et al. 1997) and for the shape of the hot side of the Li dip in the open clusters (Talon & Charbonnel 1998) also explains LiBeB observations in stars with Teff higher than 7000 K on the main sequence as well as in their evolved counterparts.
