Astronomers have conducted an experiment using a computer simulation of how a star dies, gets into a black hole.
Scientists managed to create a script absorption star black hole, writes portal Infuture . This is the central black hole, which is located in the dwarf galaxy, “the Large Magellanic Cloud” at a distance of 50 50 kiloparsecs from our own Galaxy.
“Star is literally torn from screaming at the confluence of a black hole” – say the scientists who conducted this experiment.
A giant black hole that swallowed a neighboring star, located at a distance of 3.9 billion years away in the constellation Draco.
It is reported that scientists have noticed a similar phenomenon in space, using X-ray telescopes (NASA and Japan’s Suzaku, as well as Europe’s XMM-Newton). Gravitational forces tear the star, and the remainder after the matter lies in the disk around a supermassive black hole. “The disk surrounding a black hole is hot and begins to glow. This glow is easy to see with telescopes in the X-ray range” – explain astronomers.
Previously, astronomers calculated the mass of a supermassive black hole at the frequency of radiation absorbed by the remnants of her star. Researchers analyzed flashes of gamma radiation from the Swift J1644 +57, recorded at the end of March 2011. According to scientists, it was the most vivid and powerful flash that has ever recorded by astronomers. Initially, investigators believed the cause of outbreaks of a supernova explosion, but later it was not so – supernova explosions usually fade within a few days, while the emission of Swift J1644 +57 went on for months. The source of radiation was heated flare stars of the material absorbed by the black hole.
The researchers found that the emission intensity varies with a period of 200 seconds. According to astronomers, this is due to the rotation of the accretion disk around a black hole. Based on this frequency and other characteristics of the radiation, the authors were able to calculate the approximate mass of the object, which absorbed a star. It turned out to be from 0.45 to 5 million solar masses, which is typical for the class of supermassive black holes, which can be found in the center of most galaxies.
