Two-dimensional hydrodynamic core-collapse supernova simulations with spectral neutrino transport. I. Numerical method and results for a 15 M_sun star
R. Buras, M. Rampp, H. -Th. Janka +1
Supernova models with a full spectral treatment of the neutrino transport are presented, employing the Prometheus/Vertex neutrino-hydrodynamics code with a ``ray-by-ray plus'' appr…
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…
Simulations of non-axisymmetric rotational core collapse
M. Rampp, E. Mueller, M. Ruffert
We report on the first three-dimensional hydrodynamic simulations of secular and dynamical non-axisymmetric instabilities in collapsing, rapidly rotating stellar cores which extend…
Spherically Symmetric Simulation with Boltzmann Neutrino Transport of Core Collapse and Post-Bounce Evolution of a 15 Solar Mass Star
M. Rampp, H. -Th. Janka
We present a spherically symmetric, Newtonian core-collapse simulation of a 15 solar mass star with a 1.28 solar mass iron core. The time-, energy-, and angle-dependent transport o…
Core-collapse supernova simulations: Variations of the input physics
M. Rampp, R. Buras, H. -Th. Janka +1
Spherically symmetric simulations of stellar core collapse and post-bounce evolution are used to test the sensitivity of the supernova dynamics to different variations of the input…
Supernova Explosions and Neutron Star Formation
H. -Th. Janka, K. Kifonidis, M. Rampp
The current picture of the collapse and explosion of massive stars and the formation of neutron stars is reviewed. According to the favored scenario, however by no means proven and…
