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…
Instability of a stalled accretion shock: evidence for the advective-acoustic cycle
T. Foglizzo, P. Galletti, L. Scheck +1
We analyze the linear stability of a stalled accretion shock in a perfect gas with a parametrized cooling function L ~ rho^{beta-alpha} P^alpha. The instability is dominated by the…
Multidimensional Supernova Simulations with Approximative Neutrino Transport I. Neutron Star Kicks and the Anisotropy of Neutrino-Driven Explosions in Two Spatial Dimensions
L. Scheck, K. Kifonidis, H. -Th. Janka +1
By means of two-dimensional (2D) simulations we study hydrodynamic instabilities during the first seconds of neutrino-driven supernova explosions, using a PPM hydrodynamics code, s…
