Anisotropies in Core Collapse Supernovae

Chinese Journal of Astronomy and Astrophysics, 2006
Core-collapse supernovae are the final stage of the evolution of massive stars. When these have previously lost their hydrogen and helium envelopes, the supernova explosion is classified as Type Ic. This class of supernovae are particularly interesting because of the link with long-duration Gamma-Ray Bursts.

Neutrino Oscillations in Core-Collapse Supernovae and Neutron Star Mergers

Annual Review of Nuclear and Particle Science
Accurate neutrino transport is crucial for reliably modeling explosive astrophysical events like core-collapse supernovae (CCSNe) and neutron star mergers (NSMs). However, in these extremely neutrino-dense systems, flavor oscillations exhibit challenging

Core collapse supernovae

AIP Conference Proceedings, 2007
In this contribution I highlight some of the new findings concerning core‐collapse, type II supernovae. In particular, after some comments on SN statistics, I review the case for a large spread in ejecta and Ni mass, the discovery of a population of faint, low energy events and the increasing evidences of the presence of dense circumstellar material ...

Nucleosynthesis in core collapse supernovae

AIP Conference Proceedings, 1995
Core-collapse supernovae (CCSNe) are one of the most important nucleosynthesis sites and they hold a key role in the evolution of galaxies. In the explosion, CCSNe eject freshly synthesized iron-group nuclei from explosive burning alongside of intermediate mass elements (from hydrostatic and explosive burning), and carbon and oxygen from the pre ...

Core-collapse supernovae: magnetorotational mechanism

Astronomical & Astrophysical Transactions, 2007
The results of two-dimensional numerical simulations of the magnetorotational (MR) supernova mechanism are presented. The shape of the explosion qualitatively depends on the symmetry type of the initial magnetic field. For the initial quadrupole-type magnetic field, the MR supernova explosion develops mainly near the equatorial plane while, for the ...

New regimes in the observation of core-collapse supernovae

Nature Astronomy, 2019
Core-collapse supernovae (CCSNe) mark the deaths of stars more massive than about eight times the mass of the Sun and are intrinsically the most common kind of catastrophic cosmic explosions.

Core-collapse supernova explosion simulations

Nuclear Physics B - Proceedings Supplements, 2011
Neutrinos play important roles in the pre-collapse evolution, explosion, and aftermath of core-collapse supernovae. Detected neutrino signals from core-collapse supernovae would provide insight into the explosion mechanism and unknown neutrino mixing parameters. Achieving these goals requires large-scale, multiphysics simulations.
