Supernova Explosion Traced to One of the Hottest Kind of Stars

  • Indian astronomers have tracked a rare supernova explosion and traced it to one of the hottest kind of stars called Wolf–Rayet stars or WR stars. 
  • The rare Wolf–Rayet stars are highly luminous objects a thousand times that of the Sun and have intrigued astronomers for long. 
  • They are massive stars and strip their outer hydrogen envelope which is associated with the fusion of Helium and other elements in the massive core. 
  • Tracking of certain types of massive luminous supernovae explosion can help probe these stars that remain an enigma for scientists.
  • The scientists also found that the original star was a combination of two stars – one of them is a massive WR star and another is a star much less in mass than the Sun. 
  • Supernovae (SNe) are highly energetic explosions in the Universe releasing an enormous amount of energy. 
  • Long-term monitoring of these transients opens the door to understand the nature of the exploding star as well as the explosion properties. It can also help enumerate the number of massive stars.
