IRAS 00500+6713 - The SN 1181 stellar remnant?

A study prompted by a spectrum taken by a French amateur in 2018 has found a new candidate for the stellar remnant of supernova 1181 

1.    Andreas Ritter et al 2021 ApJL 918 L33    https://iopscience.iop.org/article/10.3847/2041-8213/ac2253

The merged white dwarf remnant certainly has some extreme properties !  Here is my spectrum and guider image

Cheers
