Up: Stellar models for

1. Introduction

As in this Paper I present the results for stellar models which differ from previous papers of this series essentially in the chemical composition the description of the physics input will be not repeated here. The main characteristics and the justification for the stellar models presented are described in Claret 1995 (Paper I). Besides the difference in the initial chemical composition, I also compute the tidal constants E2 and the tidal coefficients tex2html_wrap_inline1120 for a few models of these grids. In the next papers of this series these calculations will be available for all models. Meanwhile I can provide specific calculations under request. Such parameters are very important in order to evaluate the critical times for circularization and synchronization in close binary systems (CBS) (see Claret & Cunha 1996).
