Four Indian astronomers with the Foreign Scientist traced rare Supernova Explosion with a team of foreign scientists. The Wolf-Rayet is one of the hottest and the most massive stars.
The Union Ministry of Science and technology stated on Tuesday that, “The Wolf-Rayet stars are rare and highly luminous objects a thousand times that of Sun”. After a long time, the astronomers traced the star and explosion.
Wolf-Rayet stars strip their hydrogen envelope, which is associated with the fusion of Helium and other elements in the massive core.
The ministry stated that, “The team of fours Indian astronomers from the Aryabhata Research Institute of Observational Sciences (ARIES), in Nainital, Uttarakhand state, along with the 16 scientists from the different countries have conducted the optical monitoring of one such stripped-envelop supernova. The scientist from the US, UK, Sweden, Korea, Italy and Ireland were the parts of this research. It is called SN 2015dj hosted in the Galaxy NGC 7371, last spotted in 2015”.
The scientists Anjasha Gangopadhyay, Raya Dastidar and Kuntal Mishra are working for ARIES with the Ex-member of ARIES Mridweeka Singh when the discovery found in 2015.
Mridweeka Singh told the reporters of TOI that this Supernova Explosion was found in 2015, after the discovery the scientist observed it for 170 days. Then, the team submitted the manuscript in February 2020 and was accepted in January 2021. Mridweeka Singh is a scientist and was a member of ARIES that has provided information about the supernova explosion. Currently, she is living in South Korea since 2019 and working for the Korea Astronomy and Space Science Institute.
According to a study published in the Astrophysical Journal, “The team calculated the mass of the star that is collapsed to form the Supernova as well as the geometry of its ejection”.
The team of scientist also detected that the original star was combined with two stars- Wolf-Rayet is one of the stars and another is much less than the Sun. In the universe, the supernova explosion is highly energetic that releases a massive amount of energy. The research helped the scientist to know about the nature and properties of the exploding stars.
In the Astrophysical Journal, a detailed study of the explosion was published- “SN 2015dj a type of Supernova whose progenitor was in the binary system with the mass between 13 to 20 M_sun”.
Likewise, NASA has also shared on the occasion of St. Patrick’s Day, a picture of a bluish supernova that was formed after an enormous explosion of stars. This Supernova tracked by NASA is called a Small Magellanic Cloud.
The Department of Science and Technology also stated that it can also help enumerate the number of massive stars.
