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 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.
Type Ia supernovae (SNe Ia) serve as standard candles of modern observational cosmology; they also play a vital role in galactic chemical evolution. However, the origin of these gigantic cosmic explosions remains uncertain...
