M. Arnould et al., Non-explosive hydrogen and helium burnings: abundance predictions from theNACRE reaction rate compilation, ASTRON ASTR, 347(2), 1999, pp. 572-582
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.
