Relativistic jets in Core Collapse Supernovae
After several decades of extensive research the mechanism driving core-collapse supernovae (CCSNe) is still unclear. A common mechanism is a neutrino driven outflow, but others have been proposed. Among those, a long-standing idea is that jets play an important role in SN explosions. Gamma-ray bursts (GRBs) that accompany rare and powerful CCSNe, sometimes called “hypernovae”, provide a clear e...
متن کاملUnderstanding 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...
متن کاملNeutrino-driven Convection in Core-collapse Supernovae: High-resolution Simulations
We present results from high-resolution semiglobal simulations of neutrino-driven convection in core-collapse supernovae. We employ an idealized setup with parameterized neutrino heating/cooling and nuclear dissociation at the shock front. We study the internal dynamics of neutrino-driven convection and its role in redistributing energy and momentum through the gain region. We find that even if...
متن کامل6 Neutrino - driven convection versus advection in core collapse supernovae
A toy model is analyzed in order to evaluate the linear stability of the gain region immediately behind a stalled accretion shock, after core bounce. This model demonstrates that a negative entropy gradient is not sufficient to warrant linear instability. The stability criterion is governed by the ratio χ of the ad-vection time through the gain region divided by the local timescale of buoyancy....
