PUSHing Core-Collapse Supernovae to Explosions in Spherical Symmetry II: Explodability and Global Properties

TL;DR

This study uses a parametrized spherically symmetric explosion method to systematically analyze core-collapse supernovae across a wide range of stellar masses, exploring outcomes like neutron star and black hole formation.

Contribution

It extends previous work by applying the PUSH method to a broad set of stellar models, examining explodability and final remnant types in detail.

Findings

Transition from neutron stars to black holes identified

Correlation between progenitor mass and explosion outcome established

Framework for nucleosynthesis predictions developed

Abstract

In a previously presented proof-of-principle study we established a parametrized spherically symmetric explosion method (PUSH) that can reproduce many features of core-collapse supernovae. The present paper goes beyond a specific application that is able to reproduce observational properties of SN1987A and performs a systematic study of the explosion properties for an extensive set of non-rotating, solar metallicity stellar progenitor models in the mass range from 10.8 to 120 M$_\odot$.This includes the transition from neutron stars to black holes as the final result of the collapse of massive stars, and the relation of the latter to supernovae and faint/failed supernovae. The present paper provides the basis for extended nucleosynthesis predictions in a forthcoming paper to be employed in galactic evolution models.
