Supernova Remnant Evolution: from explosion to dissipation

TL;DR

This paper models the complete evolution of a spherical supernova remnant, from explosion through various interaction phases to dissipation, revealing new insights into blast wave dynamics and phase transitions.

Contribution

It provides a comprehensive model connecting all evolutionary phases of supernova remnants, highlighting the impact of ejecta interaction on blast wave size.

Findings

Blast wave radius during adiabatic phase is smaller when ejecta interaction is considered.

New physical connections between different evolutionary phases are established.

The model offers improved understanding of supernova remnant dissipation processes.

Abstract

Here is considered the full evolution of a spherical supernova remnant. We start by calculating the early time ejecta dominated stage and continue through the different phases of interaction with the circumstellar medium, and end with the dissipation and merger phase. The physical connection between the phases reveals new results. One is that the blast wave radius during the adiabatic phase is significantly smaller than it would be, if one does notaccount for the blast wave interaction with the ejecta.
