ABSTRACT

A new code for stellar evolution, named CESAM, has been constructed at Nice by P. Morel. Standard solar models have been computed using this code. Their global characteristics, predicted capture rates of neutrinos for the chlorine and gallium experiments and their seismological properties are given and compared to the observational constraints. The emphasis is put on the effect of the recent opacities of Livermore for different mixtures, corresponding to recent abundances determination, on the neutrino predictions and the solar oscillations.
