The international group of astronomers first observed the formation of an accretion disk and a high-energy X-ray crown at a giant black hole, which was previously impossible. Article researchers Published in The Astrophysical Journal.
When small black hole holes (about 10 times higher than the mass of the Sun) absorb the material, they emit a flash of light. At the same time, they pass several stages: a black hole comes out of the state of rest, and an accretion disk is formed around it. As the substances remain less, a hot crown is formed. The whole cycle can take from several weeks to months. It was assumed that for supermassive black holes, this phenomenon proceeds very slowly, up to millennia.
In September 2018, the All-Sky Automated Survey for Supernovae (Asassn) system recorded the flash, which became the result of tidal destruction by the super-grasive black hole, which they called TDE AT2018FYK. The team collected data for two years, using Xmm-Newton X-ray telescopes and Candra X-ray Observatory, as well as Nicer, an X-ray monitoring device on board the ISS.
According to researchers, the black hole destroyed the star with the sun. In the process, it created a huge accretion disk around 12 billion kilometers wide and emptied the gas, the temperature of which was about 40,000 Kelvin. When the disk became weaker, it became dominated by the phase of the crown of high-energy X-rays.
researchers found out that it is not so in the case of tidal destruction of the star when that is suited too close to the black hole. The absorption of stellar material occurs very quickly, as in the case of small black holes.
