Simulating Anisotropic Thermal Conduction in Supernova Remnants, Implications for the Interstellar Medium

TL;DR

This paper uses simulations to study how anisotropic thermal conduction and magnetic fields affect supernova remnants and the hot gas they produce in the interstellar medium, providing detailed catalogs of hot gas properties and line widths.

Contribution

It introduces comprehensive 2.5D simulations exploring the impact of thermal conduction and magnetic fields on supernova remnants in various interstellar conditions, with detailed catalogs of hot gas volumes and line widths.

Findings

Hot gas volume depends strongly on thermal conduction and magnetic fields.

Cataloged hot gas volumes and areas across different interstellar parameters.

Simulated line widths of radioactive species provide insights into supernova ejecta.

Abstract

We present a large number of two and a half dimensional simulations of supernova remnants expanding into interstellar media having a range of densities, temperatures and magnetic field strengths. The volume of hot gas produced is strongly dependent on the inclusion of thermal conduction and magnetic fields. The four-volumes and three-areas of hot gas have been catalogued and their dependence on interstellar parameters documented. Simulated line widths of radioactive species ejected by supernovae have also been catalogued.
