Lay Summary (English)

Lay summary
Observations of supernovae and models of their explosions have improved significantly in recent years. Based on our modelling of core collapse supernovae, we plan to address key questions in nuclear astrophysics, such as the production of elements and their isotopes by making use of complete sets of thermonuclear reactions, including especially the role of neutron-induced reactions and weak interactions (beta-decays, electron/positron captures and neutrino-induced nuclear reactions). We expect major advances by (i) providing a new and expanded nuclear data base for all such reactions, (ii) performing numerical models of the explosive events with highly sophisticated radiation hydrodynamics codes which employ complete Boltzmann transport for neutrinos, and (iii) making use of observations to test the role of uncertainties in the theoretical models in terms of physics input as well as hydrodynamic modeling.
