Non-spherical core collapse supernovae III. Evolution towards homology and dependence on the numerical resolution
A. Gawryszczak, J. Guzman, T. Plewa +1
(abridged) We study the hydrodynamic evolution of a non-spherical core-collapse supernova in two spatial dimensions. We find that our model displays a strong tendency to expand tow…
The core helium flash revisited III. From Pop I to Pop III stars
Miroslav Mocak, Simon W. Campbell, Ewald Mueller +1
Degenerate ignition of helium in low-mass stars at the end of the red giant branch phase leads to dynamic convection in their helium cores. One-dimensional (1D) stellar modeling of…
Hydrodynamic simulations of the core helium flash
M. Mocak, E. Mueller, A. Weiss +1
We describe and discuss hydrodynamic simulations of the core helium flash using an initial model of a 1.25 M_sol star with a metallicity of 0.02 near at its peak. Past research con…
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…
Two-Dimensional Hydrodynamic Core-Collapse Supernova Simulations with Spectral Neutrino Transport II. Models for Different Progenitor Stars
R. Buras, H. -Th. Janka, M. Rampp +1
1D and 2D supernova simulations for stars between 11 and 25 solar masses are presented, making use of the Prometheus/Vertex neutrino-hydrodynamics code, which employs a full spectr…
Non-Spherical Core-Collapse Supernovae II. Late-Time Evolution of Globally Anisotropic Neutrino-Driven Explosions and Implications for SN 1987A
K. Kifonidis, T. Plewa, L. Scheck +2
Two-dimensional simulations of strongly anisotropic supernova explosions of a nonrotating 15 solar mass blue supergiant progenitor are presented, which follow the hydrodynamic evol…
