Two-dimensional hydrodynamic simulations of stellar core collapse are presented which for the first time were performed by solving the Boltzmann equation for the neutrino transport including a state-of-the-art description of neutrino interactions. Stellar rotation is also taken into account. Although convection develops below the neutrinosphere and in the neutrino-heated region behind the supernova shock, the models do not explode. This suggests missing physics, possibly with respect to the…

Efficient approximations of neutrino physics for three-dimensional simulations of stellar core collapse

Neutrino transport in spherically symmetric models of stellar core collapse and bounce has achieved a technically complete level, rewarded by the agreement among independent groups that a

Toward three-dimensional simulations of stellar core collapse with magnetic fields

Abstract In spherical symmetry, very reliable models of stellar core collapse, bounce, and the postbounce phase can be constructed based on general relativistic Boltzmann neutrino transport. However,

DELAYED NEUTRINO-DRIVEN SUPERNOVA EXPLOSIONS AIDED BY THE STANDING ACCRETION-SHOCK INSTABILITY

We present two-dimensional hydrodynamic simulations of stellar core collapse and develop the framework for a detailed analysis of the energetic aspects of neutrino-powered supernova explosions. Our

Standing accretion shock instability: numerical simulations of core-collapse supernova

Standing accretion shock instability (SASI) is one of the candidates to solve the mystery of why we cannot reproduce the explosion with the present core-collapse supernova models. We have studied

The role of neutrinos, rotations and magnetic fields in collapse-driven supernovae

Neutrinos are considered to be one of the most important ingredients of collapse-driven supernovae. In the last couple of years, we have seen major progress in both numerical modelling and

Sensitivity of Neutrino-Driven Core-Collapse Supernova Models to the Microphysical Equation of State

The aim of this dissertation is to explore the sensitivity of neutrino-driven core collapse supernova physics to the microphysical equation of state of the stellar matter. Core collapse supernovae
