R-process nucleosynthesis calculations with complete nuclear physics input
I. Petermann, A. Arcones, A. Kelić +8
The r-process constitutes one of the major challenges in nuclear astrophysics. Its astrophysical site has not yet been identified but there is observational evidence suggesting tha…
Influence of light nuclei on neutrino-driven supernova outflows
A. Arcones, G. Martinez-Pinedo, E. O'Connor +4
We study the composition of the outer layers of a protoneutron star and show that light nuclei are present in substantial amounts. The composition is dominated by nucleons, deutero…
Neutrino-driven wind and wind termination shock in supernova cores
A. Arcones, L. Scheck, H. -Th. Janka
The neutrino-driven wind from a nascent neutron star at the center of a supernova expands into the earlier ejecta of the explosion. Upon collision with this slower matter the wind…
Nucleosynthesis-relevant conditions in neutrino-driven supernova outflows. I. Spherically symmetric hydrodynamic simulations
A. Arcones, H. -Th. Janka, L. Scheck
We investigate the behavior and consequences of the reverse shock that terminates the supersonic expansion of the baryonic wind which is driven by neutrino heating off the surface…
