Fifty-Nine Reasons for a Supernova to not Explode

TL;DR

This paper reviews multiple reasons why supernova explosions are difficult to model accurately, highlighting the distinction between core collapse and explosion mechanisms in supernova simulations.

Contribution

It compiles and discusses fifty-nine reasons that hinder supernova explosions in numerical models, emphasizing the separation between core collapse and explosion processes.

Findings

Many numerical models overestimate explosion likelihood.

Core collapse and explosion are distinct processes.

Multiple factors prevent straightforward supernova explosions.

Abstract

The number in the title is a birthday-inspired overestimate by about an order of magnitude. Nevertheless, this contribution reminds of well-known reasons that prevented straightforward explosions in many numerical supernova models. It emphasizes a separation between the two events of core collapse and supernova explosion.
