Long-time hydrodynamical simulations of core-collapse supernovae — •Carlos Mattes1 and Almudena Arcones1,21Institut für Kernphysik, TU Darmstadt — 2GSI Helmholtzzentrum für Schwerionenforschung GmbH

Core-collapse supernovae are one of the major contributors to the chemical enrichment in the universe: they eject elements that were synthesized during the life of stars (e.g., oxygen and carbon) and they produce new and heavier elements (e.g., 1/3 of the iron in our galaxy). We will present the first long-time hydrodynamic simulations with FLASH code [1] that follow the supernova explosion from the collapse phase to several seconds after bounce. Our neutrino-driven explosions are triggered by enhancing the neutrino energy deposition [2]. In order to calculate the explosive nucleosynthesis, we have included a reduced alpha network and two equations of state that allow us to study regions from nuclear density to very low density.
