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
(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.
