Supernova Propagation in the Circumstellar and Interstellar Medium

TL;DR

This paper models supernova shock propagation through circumstellar and interstellar media, considering various structures and interactions, with implications for cosmic ray acceleration.

Contribution

It introduces a detailed analysis of supernova shock dynamics in complex media, including interactions with clouds and wind-bubbles, expanding understanding of supernova environments.

Findings

Shock waves interact with clouds and wind-bubbles.

The structure of the surrounding medium influences shock propagation.

Implications for cosmic ray acceleration are discussed.

Abstract

We describe the propagation of supernova shocks within the surrounding medium, which may be due to mass-loss from the progenitor star. The structure and density profile of the ejected material and surrounding medium are considered. Shock wave interaction with clouds and wind-bubbles, and issues relevant to cosmic rays are briefly discussed.
