Progenitor for Tycho’s supernova was not hot and luminous

An international team of scientists from the Monash University (Melbourne, Australia), the Towson and Pittsburgh Universities (USA) and the Max Planck Institute for Astrophysics, has shed new light on the origins of the famous Tycho’s supernova. The research, published in Nature Astronomy, debunks the common view that Tycho’s supernova originated from a white dwarf, which had been slowly accreting matter from its companion in a binary system.
