The Role of Fission in Neutron Star Mergers and its Impact on the r-Process Peaks
Marius Eichler, Almudena Arcones, Alexandra Kelic +10
Comparing observational abundance features with nucleosynthesis predictions of stellar evolution or explosion simulations can scrutinize two aspects: (a) the conditions in the astr…
On the nuclear robustness of the r process in neutron-star mergers
Joel de Jesús Mendoza-Temis, Meng-Ru Wu, Karlheinz Langanke +3
We have performed r-process calculations for matter ejected dynamically in neutron star mergers based on a complete set of trajectories from a three-dimensional relativistic smooth…
Local and global effects of beta decays on r-process
O. L. Caballero, A. Arcones, I. N. Borzov +2
Nuclear beta decay rates are an essential ingredient in simulations of the astrophysical r-process. Most of these rates still rely on theoretical modeling. However, modern radioact…
Astrophysical weak-interaction rates for selected and nuclei
G. Martínez-Pinedo, Y. H. Lam, K. Langanke +2
We have evaluated the electron capture rates on Ne, F, Mg, Na and the decay rates for F and Na at temperature and density conditions r…
