A black hole 11 times more massive than the Sun has been discovered

An international group of astronomers reports the discovery of a black hole in a globular cluster known as NGC 1850. This object, which is part of a binary system, belongs to stellar-mass black holes and is about 11 times more massive than the Sun. Details about the opening are available in the preprint repository arXiv.org.

To date, scientists have reported only a few direct detections of black holes that are located in binary systems inside star clusters. Such black holes look like an invisible object around which a large star rotates. Moreover, no direct dynamic detection of a black hole in a young massive cluster has been reported so far. The discovery of such objects may be crucial for understanding the early dynamic evolution of black holes in high-density environments.

The object designated as NGC 1850 BH1 was discovered in NGC 1850, a young (about 100 million years old) and massive (with a mass of about 100 thousand solar masses) globular cluster in the Large Magellanic Cloud. It consists of a black hole and a main-sequence star that is about 4.9 times more massive than the Sun. The period of rotation is 5.04 days, and the inclination of the orbit is 38 degrees.

It is expected that in the future the star will turn into a giant, which will lead to the transfer of matter from it to the black hole and the appearance of X-rays. Mass transfer is likely to end when most of the hydrogen shell of the donor star is transferred to the companion, and the core of the helium star remains. Eventually, there will be a pair of black holes — a white dwarf.
