Core-Collapse Supernovae at the Threshold

Despite of still bothering uncertainties and ongoing controversy, the convectively supported neutrino-heating mechanism (1) must be considered as a promising way to explain supernova explosions of massive stars. Neutrinos drive the evolution of the collapsing stellar core and of the forming neutron star and dominate the event energetically by carrying away about 99% of the gravitational binding...

Understanding Core-Collapse Supernovae

At the University of Arizona, we have a major effort to study core-collapse supernovae, neutrino opacities and transfer, multi-dimensional radiation hydrodynamics, pulsar kicks, and gravitational radiation from supernovae. We have developed a precision 1D (spherical) multigroup implicit Boltzmann solver, SESAME 1 [1, 2], using the Feautrier technique, with the tangent-ray method to achieve exce...

A Model for Gravitational Wave Emission from Neutrino-driven Core-collapse Supernovae

Using a suite of progenitor models (12, 15, 20 and 40 M⊙) and neutrino luminosities in two-dimensional (2D) simulations, we investigate the gravitational-wave (GW) emission from postbounce phases of core-collapse supernovae (CCSNe). We characterize the matter GW signatures of prompt convection, steady-state convection, the standing accretion shock instability (SASI) , and asymmetric explosions....

Non - spherical core collapse supernovae

Two-dimensional simulations of strongly anisotropic supernova explosions of a nonrotating 15 M ⊙ blue supergiant progenitor are presented, which follow the hydrodynamic evolution from times shortly after shock formation until hours later. It is shown that explosions which around the time of shock revival are dominated by low-order unstable modes (i.e. by a superposition of the l = 2 and l = 1 m...

Progenitors of core-collapse supernovae

Knowledge of the progenitors of core-collapse supernovae is a fundamental component in understanding the explosions. The recent progress in finding such stars is reviewed. The minimum initial mass that can produce a supernova has converged to 8± 1M⊙, from direct detections of red supergiant progenitors of II-P SNe and the most massive white dwarf progenitors, although this value is model depend...
