Lithium Depletion in PreMain-Sequence Solar-like Stars

摘要

We examine the internal structure of solar-like stars in detail between 0.8 and 1.4 M and during premain-sequence phase. Recent opacity computations of OPAL along with a new hydrodynamical mixing process have been considered. We also introduce up-to-date nuclear reaction rates and explore the impact of accretion, mixing length parameter, nonsolar distributions among metals, and realistic rotation history. Models predict lithium depletion that we compare to the ~7Li content observations of the Sun and four young clusters of different metallicities and age.
