Dust and Ices in the SNR

TL;DR

This paper investigates the presence and survival of dust and water ice in supernova remnants using observational data from infrared observatories and preliminary theoretical modeling, highlighting potential detections and the need for further study.

Contribution

It provides new observational evidence and initial models suggesting water ice can exist in supernova remnants under specific conditions.

Findings

Water ice may be present in IC 443 and other SNRs.

The 62 μm emission could be from water ice or [OI] emission.

Water ice could survive in SNRs under certain densities and temperatures.

Abstract

The presence of dust in supernova remnants (SNRs) is confirmed by extensive infrared data from observatories such as Spitzer, Herschel, and JWST, alongside theoretical models of dust formation. This study explores the existence of dust and ices, particularly water ice via 62 {\mu}m in SNRs such as the Crab Nebula and N49, using observational data and preliminary modeling with Cloudy. Observations suggest that water ice may be present in IC 443 and possibly other remnants, though the 63 {\mu}m band could also indicate [OI] emission. Theoretical models indicate that water ice could survive under certain conditions in SNRs, with densities and temperatures analyzed. Further observations and refined simulations are needed to confirm these findings.
