The First Second of a Type II Supernova: Convection, Accretion, and Shock Propagation
The First Second of a Type II Supernova: Convection, Accretion, and Shock Propagation
One- and two-dimensional hydrodynamical simulations of the neutrino-driven supernova explosion of a 15 M☉ star are performed for the phase between stagnation of the prompt shock and 1 s after core bounce. Variation of the neutrino (ν) fluxes from the ν sphere shows that explosion energy and timescale, initial proto-neutron …
