(Claret+, 1997) ================================================================================ Stellar models for a wide range of initial chemical compositions until helium burning. III. From X=0.55 to X=0.75, for Z=0.03 Claret A. =1997A&AS..125..439C (SIMBAD/NED BibCode) ================================================================================ ADC_Keywords: Models, evolutionary Keywords: stellar evolution - chemical composition - binary stars - apsidal motion Abstract: In this Paper I present grids for the stellar models with a slightly higher metallic content than in the previous works (Claret, 1995A&AS..109..441C; Claret & Gimenez, 1995A&AS..114..549C), say, Z=0.03. The initial helium abundances in mass are Yi=0.42, 0.32 and 0.22; this last value was used only to facilitate interpolations since it is a little bit smaller than the primordial helium abundance. The present computations are based on the radiative opacities with spin-orbi t coupling provided by the Lawrence Livermore group (Iglesias et al., 1992ApJ...397..771I). For the lower temperatures I have used the results by Alexander (1992, priv. comm.). Core overshooting was taken into account as well as mass loss. The models presented here cover the mass range between 1 and 40M{sun}. I also compute for all models the internal structure constants kj and the radius of gyration ß. For the first time the calculation of the tidal constants E2 and {lambda}2, which are used to evaluate circularization and synchronization times in binary stars, are presented for stellar models as a function of the initial mass and time. The former is related with the dynamical tidal contribution to the total perturbed potential in a binary star while the latter is connected with the external structure of the outer layers.
