Exploiting the neutronization burst of a galactic supernova
M. Kachelriess, R. Tomas, R. Buras +3
One of the robust features found in simulations of core-collapse supernovae (SNe) is the prompt neutronization burst, i.e. the first milliseconds after bounce when the SN…
Neutrino-Driven Supernovae: an Accretion Instability in a Nuclear Physics Controlled Environment
H. -T. Janka, R. Buras, F. S. Kitaura Joyanes +3
New simulations demonstrate that low-mode, nonradial hydrodynamic instabilities of the accretion shock help starting hot-bubble convection in supernovae and thus support explosions…
Supernova Asymmetries and Pulsar Kicks -- Views on Controversial Issues
H. -Th. Janka, L. Scheck, K. Kifonidis +2
Two- and three-dimensional simulations demonstrate that hydrodynamic instabilities can lead to low-mode (l=1,2) asymmetries of the fluid flow in the neutrino-heated layer behind th…
Global Anisotropies in Supernova Explosions and Pulsar Recoil
L. Scheck, T. Plewa, K. Kifonidis +2
We show by two-dimensional and first three-dimensional simulations of neutrino-driven supernova explosions that low (l=1,2) modes can dominate the flow pattern in the convective po…
Core-Collapse Supernovae: Modeling between Pragmatism and Perfectionism
H. -Th. Janka, R. Buras, F. S. Kitaura Joyanes +2
We briefly summarize recent efforts in Garching for modeling stellar core collapse and post-bounce evolution in one and two dimensions. The transport of neutrinos of all flavors is…
Non-stationary hyperaccretion of stellar-mass black holes in three dimensions: Torus evolution and neutrino emission
S. Setiawan, M. Ruffert, H. -Th. Janka
We present three-dimensional hydrodynamic simulations of the evolution of selfgravitating, thick accretion discs around hyperaccreting stellar-mass black holes. The black hole-toru…
