New grids of stellar models. II.

In order to take into account the uncertainties in the metal content we computed two grids with different metallicities: Z=0.002 and Z=0.004. The covered mass range is from 0.8 up to 125M_{sun} and the models are followed until the exhaustion of carbon in the core, for the more massive ones.

We have introduced a recent measurement of the nuclear rate ^14^N(p,{gamma})^15^O. A comparison among models with the old and new rate was carried out revealed that the former are slightly hotter than the first ones. Such differences depend on the mass range. The opacities, the equation of state, the remaining nuclear reactions rates, the core overshooting parameterization and the convective transport of energy are the same as discussed previously by us.
