An article published in the journal “Science” describes a research on the remnants of a strange supernova cataloged as LP 40-365. According to a team led by Stephane Vennes of the Astronomical Institute of Czech Academy of Sciences in Ondrejov, Czech Republic, that’s a type Iax supernova. It only partially destroyed a white dwarf leaving a part that moves at a very high speed and has an abnormal composition for that dead star type.
