Hubble Spots Progenitor of a Rare Type of Supernova

Using data from observations made in the last two decades using the Hubble Space Telescope researchers say they have spotted ‘zombie stars.’ The study is described in the journal Nature.

After a supernova, the star is completely destroyed and the materials scattered in space. However there are weaker explosions known as Type Iax whereby the remnants of the explosion find new life. The zombie which created the supernova has been named SN 212 Z.

The researchers say two stars initially existed, a large one and a companion which as smaller. Hydrogen left the larger star for the smaller one. With time the smaller one grew in size and engulfed the larger one. The larger one became a white dwarf. A weaker explosion eroded the outer layers of the initially small star leaving behind a helium core and the white dwarf.
