Extending the susy model to core-collapse supernovae

TL;DR

This paper explores extending a supersymmetric model for type Ia supernovae to also explain core-collapse supernovae, aiming for a unified theoretical framework despite their different timescales.

Contribution

It investigates the potential of a supersymmetric phase transition to unify the explanations of both supernova types within a single model.

Findings

Supersymmetric model can potentially explain both supernova types

Phase transition timing may account for different supernova delays

Unified supernova model offers new theoretical insights

Abstract

A notable feature of the two standard models for thermonuclear and core-collapse supernovae is that, although these two models are fundamentally different, the respective supernova types have quite similar rates and appearances. For instance, both types occur one to several times per century per typical galaxy and both types seed the universe with the heavy elements essential to life. In spite of this, neither standard model provides a reasonably problem-free description of its target phenomenon. A major obstacle to providing a unified picture of supernovae would seem to be the fact that type Ia supernovae occur typically with gigayear delay times after the cessation of carbon fusion while the core-collapse explosions occur only days after such fusion cessation. In this article we study the possibility of extending the successful supersymmetric model for type Ia supernovae to core-collapse events. The question is whether and under what assumptions a phase transition to an exact supersymmetric background can efficiently explain both type Ia and core collapse supernovae.
