Four Indian astronomers join foreign scientists to track rare supernova explosion India news



New Delhi: A team of four Indian astronomers and international collaborators tracked a rare supernova explosion and traced it back to one of the hottest stars called the Wolf-Rayet star (WR star), which is a thousand times that of highly luminous objects sun.
WR stars are massive stars and deprive their outer hydrogen envelope, which is related to the fusion of helium and other elements in the massive nucleus. Tracking certain types of large-scale supernova luminous explosions can help detect these stars, which remain a mystery for scientists around the world.
Four Indian scientists from the Aryabhatta Institute of Observational Sciences (ARIES), Nainital, This is an autonomous research institute under the Ministry of Science and Technology, from the United States, Britain, Canada, Ireland, Italy, Sweden South Korea and South Korea have carried out optical surveillance of such a shelled supernova SN 201
5dj hosted in Galaxy NGC 7371. They calculated the mass of the star that collapsed to form a supernova and the geometry of its ejection. Scientists have also discovered that the primordial star is a combination of two stars-one of which is a huge WR star, and the other is a star with a much smaller mass than the sun.

Mridweeka Singh, from South Korea, was a member of ARIES when he discovered the supernova. He is a member of ARIES. He said: “The supernova was discovered in 2015. Since the discovery, we have been observing supernovae for 170 days. Since then. , We submitted the manuscript in February last year and was accepted on January 22 this year. The paper is now available online and is being published.”
Mridweeka, who moved to South Korea in 2019 after leaving the institute, told the Korea Institute of Astronomy and Space Science

“SN 2015dj is a type Ib supernova whose ancestor was in a binary star system with a mass of 13 to 20 M_sun. The exploding geometry of this supernova is symmetrical.” The group’s findings and detailed research were recently published in ” Astrophysical Journal‘.
Supernovae (SNe) are high-energy explosions in the universe that release large amounts of energy. Long-term monitoring of these transients has opened the door to understanding the nature of exploding stars and the characteristics of explosions. It can also help enumerate the number of massive stars.
