Degeneracy breakdown as a source of supernovae Ia

TL;DR

This paper explores a supersymmetric phase transition model as a mechanism for sub-Chandrasekhar supernovae Ia, analyzing its ability to explain observed rates, delay times, and remnant characteristics.

Contribution

It introduces a novel supersymmetric phase transition model for SNIa explosions and evaluates its consistency with observed supernova properties and remnants.

Findings

Model fits total SNIa rate and delay time distribution

Predicts low-mass black hole remnants as SNIa aftermath

Suggests potential detection of supersymmetric remnants

Abstract

We pursue the investigation of a model for sub-Chandrasekhar supernovae Ia explosions (SNIa) in which the energy stored in the Pauli tower is released to trigger a nuclear deflagration. The simplest physical model for such a degeneracy breakdown is a phase transition to an exactly supersymmetric state in which the scalar partners of protons, neutrons, and leptons become degenerate with the familiar fermions of our world as in the supersymmetric standard model with susy breaking parameters relaxed to zero. We focus on the ability of the susy phase transition model to fit the total SNIa rate as well as the delay time distribution of SNIa after the birth of a progenitor white dwarf. We also study the ejected mass distribution and its correlation with delay time. Finally, we discuss the expected SNIa remnant in the form of a black hole of Jupiter mass or lower and the prospects for detecting such remnants.
