Indian astronomers have followed a rare supernova explosion to one of the hottest stars, known as Wolf-Wright stars or WR stars. Wolf-Wright’s rare stars are very luminous objects, a thousand times that of the sun and have long been intriguing to astronomers, according to an official statement from the Union’s Ministry of Science and Technology.
They are massive stars and strip off their outer hydrogen shell associated with the fusion of helium and other elements in the massive core.
Tracking certain types of massive glowing supernovae can help investigate these remaining stars and a riddle for scientists.
A team of astronomers from the Aryabhatta Observatory (ARIES) Research Institute at Nanital, together with international collaborators, performed the supernova optical monitoring of such an exposed shell named SN 2015dj hosted in the 2015 observed NGC 7371 galaxy.
They calculated the mass of the star that collapsed to form the supernovae as well as the geometry of its emission, according to a study published in The Astrophysical Journal.
The scientists also discovered that the original star is a combination of two stars – one of which is a massive WR star and another is a star much less in mass than the Sun.
Supernovae are very energetic explosions in the universe that release a huge amount of energy.
Long-term monitoring of these transitions opens the door to understanding the nature of the exploding star as well as the properties of the explosion. It can also help count the number of massive stars.
