This article carried out three-dimensional core-collapse supernova simulations with and without aspherical velocity perturbations to assess their potential impact on the supernova hydrodynamics in the stalled-shock phase.Abstract:
Multi-dimensional simulations of advanced nuclear burning stages of massive stars suggest that the Si/O layers of presupernova stars harbor large deviations from the spherical symmetry typically assumed for presupernova stellar structure. We carry out three-dimensional core-collapse supernova simulations with and without aspherical velocity perturbations to assess their potential impact on the supernova hydrodynamics in the stalled-shock phase. Our results show that realistic perturbations can qualitatively alter the postbounce evolution, triggering an explosion in a model that fails to explode without them. This finding underlines the need for a multi-dimensional treatment of the presupernova stage of stellar evolution.read more

A two-parameter criterion for classifying the explodability of massive stars by the neutrino-driven mechanism
TL;DR: In this paper, the authors identify two parameters computed from the pre-collapse structure of the progenitor, which in combination allow for a clear separation of exploding and non-exploding cases with only few exceptions (1.5%) in a set of 621 investigated stellar models.

Physics of Core-Collapse Supernovae in Three Dimensions: a Sneak Preview
TL;DR: The first successful neutrino-driven supernova explosion was obtained with self-consistent, first-principles simulations in three spatial dimensions as discussed by the authors, where 3D turbulence leads to energy cascading from large to small spatial scales, thus disfavoring the growth of buoyant plumes on the largest scales.
