Abstract:
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 (1991) 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.
