New generation stellar models with rotation and internal gravity waves: The Li dip revisited

Abstract

In this paper we explore the consequences ofthe interaction between internal gravity waves,rotation-induced mixing and atomic diffusion on the rotation profile and internal element distribution of main sequence low-mass stars.We present the first fully hydrodynamical models that include self-consistentlyelement and angular momentum redistribution by these three mechanisms.We show how internal gravity waves extract angular momentum from the deep stellar interior and shape the internal rotation profile of solar-type stars. We compare predictions of our models with lithium observations in open cluster stars.
