Supernova explosion Wolf-Rayet stars

A team of four Indian astronomers, along with international collaborators, has tracked a rare supernova explosion and traced it to one of the hottest kind of stars called Wolf–Rayet stars (WR stars), which are highly luminous objects a thousand times that of the Sun. WR stars are massive stars and strip their outer hydrogen envelope, which is associated with the fusion of Helium and other elements in the massive core. 

About ​Supernovae (SNe)
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.
