A class of supernova survivors

Group members and collaborators have laid claim to a new class of zombie stars that are shattered remnants of thermonuclear supernova that did not fully disrupt the white dwarf! Led by Roberto Raddi at Dr.Karl-Remeis-Sternwarte Bamberg, we have now published at least three likely members of this new class of star named after the prototype LP 40-365.

The research is well summarized by Shannon Hall writing in Scientific American: This “newly discovered class of odd stars appears to have persevered through supernova explosions — providing a rare glimpse into these astrophysical catastrophes.” Another summary is detailed in a Twitter thread: https://twitter.com/jotajotahermes/status/1096054102327525376?s=20.
