Abstract:
New grids of stellar evolutionary models are presented for a wide
range of initial hydrogen content around the solar composition. These
compositions are (X, Z) = (0.80, 0.02), (0.70, 0.02) and (0.60, 0.02).
Recent OPAL opacities with LS coupling and Grevesse composition were
adopted, and Alexander's tables were used for lower temperatures. We
consider models with core overshooting with {alpha}_ov_=0.20, and
mixing length parameter l/H_p_=1.52 that seems to represent well
double-lined eclipsing binary stars. Mass loss during the main
sequence and in the red giant phase were taken into account. The
nuclear network treats 14 isotopes and optionally the lithium burning
to study its depletion in less massive models during pre main sequence
evolution. The mass range covered goes from 1 up to 40M_{sun}_ and
the more massive models were followed until helium burning.
