Explosion Mechanisms of Core-Collapse Supernovae

Abstract

Core-collapse supernovae have long attracted attention of astrophysicists because they have many facets playing important roles in astrophysics. In spite of such importance and rigorous studies for several decades, we still do not understand the explosion mechanism completely. Recently 3D neutrino-driven models have been reported, for the first time, in the context of self-consistent supernova simulations. Keeping step with very rapid advancements of hard/softwares in supercomputing, supernova codes are being updated with sufficient realism to deal with seven-dimensional Boltzmann neutrino transport in the near future. We are going to pin down the mechanism of explosion by deciphering multi-messenger signatures from these first-principle models, such as gravitational waves, neutrinos, and nucleosynthetic yields, with forthcoming observations by next-generation detectors (surely) being on-line in the decade to come.
