Abstract
The abundances of the isotopes of the elements from C to Al produced by the non-explosive CNO, NeNa and MgAl modes of hydrogen burning, as well as by helium burning, are calculated with the thermonuclear rates recommended by the European compilation of reaction rates for astrophysics (NACRE). The im pact of nuclear physics uncertainties on the derived abundances is discusse d in the framework of a simple parametric astrophysical model. These calcul ations have the virtue of being a guide in the selection of the nuclear unc ertainties that have to be duly analyzed in detailed model stars, particula rly in order to perform meaningful confrontations between abundance observa tions and predictions. They are also hoped to help nuclear astrophysicists pinpointing the rate uncertainties that have to be reduced most urgently.
