... 1997, Schröder 1998). Because of the low mass and a nonconvective core, solar evolution models are, however, not subject to any MS (main sequence) core-overshooting. In use, the code is very fast, and mass-loss is accepted simply as an outer boundary condition. As already pointed out by VandenBerg ...
