Study MIT said all black holes underwent a similar accession cycle

MIT researchers have conducted studies into black holes from various sizes. On September 9, 2018, incident happened when astronomers spied on a flash of light from a galaxy around 860 million light years. The source of flash of light is a supermassive black hole about 50 times the sun that is usually very quiet.

Light flashes were made when the black hole consumed a star that passed nearby in a rare event known as a tidal disorder event. When the star debris falls towards the black hole, a large amount of energy in the form of light seen is released. Researchers from MIT and other organizations use many telescopes to watch events revealed. They observed something interesting because the supermasive black hole showed properties similar to a large star-black hole which was much smaller.

The results showed that added growth, which is a way of black holes evolved when they consumed materials, not depending on their size. The study writer Dheeraj Pashham said that the team had shown if you have seen one black hole, you have seen everything in a sense. The researchers noted that when a small black-star hole about ten times the mass of the Sun emitted a light explosion, usually in response to the entrance wave of a companion star.

The radiation explosion triggers certain evolution from the area around the black hole which converts it into a “soft” phase that is dominated by an accretion disk because the star material is pulled into a black hole. When the inclusion of material decline, the transition of the black hole became a “hard” phase where the white-sexy corona took over. Finally, the black hole settled into a stable quietscence with the entire cycle lasted several weeks to months.

For supermasive black holes, scientists believe the process will be too long to be captured completely because they usually feed slowly in the Galaxy Central Area. In supermassive black holes, the process usually occurs in the range of timescales thousands of years. The whole process accelerates when the black hole experiences sudden and massive matter flows, such as during the tidal disorder event when the star is quite close to the black hole so that it can be torn torn. The star in this example that is forced to be interrupted is about the size of the sun that produces an accretion disk of around 12 billion kilometers wide.
