The Radiance Exceeds the Host Galax 4 Times

Directly hit the black hole and tear the star through the process, the radiance exceeds the host galax 4 times.
When a star is too close to a black hole, the end is dragged by the latter’s huge gravitational force, but when scientists find similar events in the past, the star has usually been torn apart. Recently, the NASA satellite fortunately hit a black hole with a mass of 6.3 million times in the distance, and swallowed a star of similar mass to the sun from beginning to end. This rare event was named ASASSN-19.
There are many unimaginable violent events in the universe, such as quasars, supernova explosions, gamma-ray bursts, etc. The radiant energy released by a supernova explosion can be equivalent to the total radiation energy of the sun, and the process of sudden electromagnetic Radiant energy illuminates the entire galaxy. Although it lasts for a short time, in the Milky Way, there is one supernova explosion in an average of one century.
In contrast, black hole eating events become rare, about once every 10,000 to 100,000 years; and if we want to witness a star close to the black hole, the process of tearing through the black hole is completely difficult. Fortunately, the NASA Transit Excavator Satellite (TESS) recently captured this rare astronomical wonder from the 2MASX J07001137-6602251 galaxy of 375 million light-years away.
The event, named ASASSN-19bt, is a sun-sized star that is too close to a supermassive black hole, crossing the so-called “Roche limit” – the bottom line of two celestial bodies, once crossed the balance The black hole tidal force will gain overwhelming force to start shredding the small celestial body, which is also known as the tidal disruption event (TDE).
According to NASA, TESS saw a steady increase in luminosity near the black hole within 41 days, even four times brighter than the host galaxies, representing a shredded stellar material forming a black hole accretion disk that was released during high-speed friction. High-energy radiation; in addition, TESS records that the ASASSN-19bt event will continue to improve while the luminosity continues to increase, and will experience a brief cooling (temperature from 40,000 ° C to 20,000 ° C) to stabilize, this information can help other scientists to distinguish Many cosmic outbreaks.
The new paper is published in The Astrophysical Journal and can be viewed on the arXiv website.
