    Very cool. Any ideas how it could have survived the SN event?

    Successful detonation is not guaranteed. It depends on many factors. In particular the mass accretion / loss history, the point where the detonation initiates, how much of an envelope is above the ignition point, etc. Just as a chemical explosive can fizzle so can a SN.

    Perhaps rather than the usual scenario where a wd accretes excess material until it collapses as a whole some fluke in the accretion history started an off center detonation the ejected enough material to relieve the critical pressure on the core. If the detonation was initiated be a sudden supersonic flow or merger event the CO core would not have had time to respond and detonate as a whole, just in part. I'm speculating.....
