SNR 0519−69.0 as a Type Ia Explosion in a Planetary Nebula Cocoon
Abstract The degree to which Type Ia Supernova (SN Ia) progenitors modify their surroundings remains an open question. In this work, we explore the parameter space for circumstellar interaction in Type Ia Supernova Remnant (SNR) 0519−69.0 by comparing observed archival Chandra spectra with model SNR spectra calculated assuming different SN Ia explosion scenarios and ambient medium (AM) structures. We compared SNR models expanding into a uniform AM with those expanding into a post-common envelope cocoon generated from a planetary nebula model. We conclude that the X-ray spectra and bulk dynamics of SNR 0519−69.0 are best explained by an interaction with a planetary nebula cocoon, implying that the progenitor of this SN Ia went through a common envelope episode shortly (~10,000 yr) before the SN explosion.
