Rare superluminous supernova

In news

An extremely bright, hydrogen deficient, fast-evolving supernova that shines with the energy borrowed from an exotic type of neutron star with an ultra-powerful magnetic field has been spotted by Indian researchers.

Significance
  • Deep study of such ancient spatial objects can help probe the mysteries of the early universe.
Supernova
  • Such type of supernovae called SuperLuminous Supernova (SLSNe) is very rare.
  • This is because they are generally originated from very massive stars (the minimum mass limit is more than 25 times that of the Sun), and the number distribution of such massive stars in our galaxy or in nearby galaxies is sparse.
  • The team observed it using special arrangements at India’s recently commissioned Devasthal Optical Telescope (DOT-3.6m) along with two other Indian telescopes: Sampurnanand Telescope-1.04m and Himalayan Chandra Telescope-2.0m.
  • They found that the outer layers of the onion structured Supernovae had been peeled off, and the core was shining with a borrowed energy source.
