J/A+AS/96/269Stellar Models from 0.8 to 120 Msolar (Schaller+, 1992)

New grids of stellar models from 0.8 to 120 Msolar at Z=0.020 and Z=0.001 Schaller G., Schaerer D., Meynet G., Maeder A. <Astron. Astrophys. Suppl. Ser. 96, 269 (1992)> =1992A&AS...96..269SADC_Keywords: Models, evolutionary ; Mass loss ; Stars, supergiant; Stars, Wolf-RayetKeywords: stars: evolution - mass loss - supergiants - Wolf-RayetAbstract: New grids of stellar evolutionary models covering the range of 0.8 to 120 solar masses have been computed for metallicites Z=0.020 and Z=0.001. The models use the new opacities by Rogers and Iglesias (1992ApJS...79..507R) and by Kurucz (1991) at low T. The consequent changes in the solar helium content, in the mixing length ratio and in the overshooting parameter are taken into account after careful calibrations. Important physical ingredients as the nuclear reaction rates and the neutrino loss rates have been updated. The ionization of the main heavy elements is calculated in details. Results of the models are given in a compact way at corresponding evolutionary stages in each model. In addition to the tables, we shortly present some general results on the tracks in the HR diagrams, the lifetimes in the H-, He-, C-burning phases, and on massive and WR stars.File Summary:
