Simulation of neutrino-driven winds from core-collapse supernovae — •Maximilian Witt1 and Almudena Arcones1,2 — 1Institut für Kernphysik, TU Darmstadt, Germany — 2GSI Helmholtzzentrum für Schwerionenforschung GmbH, Darmstadt, Germany
Neutrino-driven winds occur after core-collapse supernovae, when the hot proto-neutron star cools by radiating neutrinos. Within the continuous mass outflow that is ejected at supersonic velocities, heavy elements up to silver may form [1].
We have developed a steady-state model that was used to compare to our 1D and 2D hydrodynamic simulations. We have investigated the conditions which lead to a neutrino-driven wind and will discuss how this affects the nucleosynthesis in core-collapse supernovae.
