The r-process of stellar nucleosynthesis: Astrophysics and nuclear physics achievements and mysteries
M. Arnould, S. Goriely, K. Takahashi
The r-process, or the rapid neutron-capture process, of stellar nucleosynthesis is called for to explain the production of the stable (and some long-lived radioactive) neutron-rich…
Extragalactic cosmic-ray source composition and the interpretation of the ankle
D. Allard, E. Parizot, A. V. Olinto +2
We consider the stochastic propagation of high-energy protons and nuclei in the cosmological microwave and infrared backgrounds, using revised photonuclear cross-sections and follo…
Analytical representations of unified equations of state of neutron-star matter
P. Haensel, A. Y. Potekhin
Analytical representations are derived for two equations of state (EOSs) of neutron-star matter: FPS and SLy. Each of these EOSs is unified, that is, it describes the crust and the…
Uncertainties in the Th cosmochronometry
S. Goriely, B. Clerbaux
Recent observations of r-nuclei, and in particular of Th, in ultra-metal poor stars revived the old idea that the Th cosmochronometry could provide an age estimate of the oldest st…
Non-explosive hydrogen and helium burnings: Abundance predictions from the NACRE reaction rate compilation
M. Arnould, S. Goriely, A. Jorissen
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…
The survival of 205Pb in intermediate-mass AGB stars
Nami Mowlavi, Stephane Goriely, Marcel Arnould
The now extinct 205Pb is a pure s-process radionuclide (t_{1/2} = 1.5x10^7 y) of possible substantial cosmochemical interest. As a necessary complement to the detailed theoretical…
