New reaction rate for 16O(p,gamma)17F and its influence on the oxygen isotopic ratios in massive AGB stars
C. Iliadis, C. Angulo, P. Descouvemont +2
The 16O(p,gamma)17F reaction rate is revisited with special emphasis on the stellar temperature range of T=60-100 MK important for hot bottom burning in asymptotic giant branch (AG…
Relation between the 16O(alpha,gamma)20Ne reaction and its reverse 20Ne(gamma,alpha)16O reaction in stars and in the laboratory
P. Mohr, C. Angulo, P. Descouvemont +1
The astrophysical reaction rates of the 16O(a,g)20Ne capture reaction and its inverse 20Ne(g,a)16O photodisintegration reaction are given by the sum of several narrow resonances an…
Compilation and R-matrix analysis of Big Bang nuclear reaction rates
Pierre Descouvemont, Abderrahim Adahchour, Carmen Angulo +2
We use the R-matrix theory to fit low-energy data on nuclear reactions involved in Big Bang nucleosynthesis. A special attention is paid to the rate uncertainties which are evaluat…
Cross section predictions for hydrostatic and explosive burning
P. Descouvemont, T. Rauscher
We review different models used for reactions involved in nuclear astrophysics. The reaction rate is defined for resonant as well as for non-resonant processes. For low-density nuc…
Updated Big-Bang Nucleosynthesis compared to WMAP results
Alain Coc, Elisabeth Vangioni-Flam, Pierre Descouvemont +2
From the observations of the anisotropies of the Cosmic Microwave Background (CMB) radiation, the WMAP satellite has provided a determination of the baryonic density of the Univers…
Updated Big Bang Nucleosynthesis confronted to WMAP observations and to the Abundance of Light Elements
A. Coc, E. Vangioni-Flam, P. Descouvemont +2
We improve Standard Big Bang Nucleosynthesis (SBBN) calculations taking into account new nuclear physics analyses (Descouvemont et al. 2003). Using a Monte-Carlo technique, we calc…
