A rare supernova explosion has been discovered by Indian astronomers. The explosion belongs to one of the hottest kinds of stars called Wolf Rayet stars or WR stars.
With high brightness, these stars have kept astronomers intrigued for a long time. Wolf-Rayet stars, the massive stars, remove their outer hydrogen envelope.
The outer hydrogen removal is associated with the fusion of Helium and others elements.

“Tracking of certain types of massive luminous supernovae explosion can help probe these stars that remain an enigma for scientists,” the Ministry of Science and Technology said in a release.
The astronomers from Aryabhatta Research Institute of Observational Sciences (ARIES) in Nainital, Uttarakhand, and their international collaborators optically monitored a supernova called SN 2015dj hosted in the galaxy NGC 7371. This galaxy was discovered in 2015, the ministry said in a statement.
The astronomers engaged in the study calculated the mass of the star that collapsed to constitute a supernova. The study was published in The Astrophysical Journal. According to the scientists, the original was comprised of two stars.
