On 27 November a team of scientists from the National astronomical Observatory of China (NAOK) reported the discovery of a binary system LB-1 in the galaxy the milky Way. A companion star in a binary system were so massive black holethat, according to the General theory of relativity and our knowledge about star formation, should not exist. The mass of the black hole exceeds the mass of the Sun 70 times. However, despite the fact that the authors of the study checked data for three years, their conclusionsare likely wrong. This became known thanks to three different studies in which the revised results obtained by Chinese astronomers. It turned out that the black hole in the system LB-1 is actually not such a massive.
The Central thesis of all three articles, which, coincidentally, was published around the same time, is that the light that is interpreted as coming from LB-1 could come from a completely different source. In the original article astronomers led by Stefanom Liu of the National astronomical Observatory of China claimed in a binary system LB-1 there is a black hole, located at a distance 15 thousand light years from Earth, and its mass is 70 times greater than the mass of the Sun. Initially, the group of researchers called the discovery impossible and in the end was right. The fact that stars have the potential to form a black hole, usually complete their life cycle collapsebut in a neutron star or a black hole, which is a guarantee of education is not a supermassive black hole. And if such “impossible” the black hole existed, would change our understanding of the formation and the astrophysics of these cosmic monsters.

Why the astronomers were wrong?
Three separate teams of researchers from the University of California at Berkeley, the University of Auckland in New Zealand University and K. U. Leuven in Belgium, shared his insights here, here and here. It turned out that Chinese astronomers misinterpreted the data. According to the results of three independent studies in the binary system LB-1 is really an invisible object that is probably a black hole, but its mass is 5-20 solar masses, not 70. The error has arisen from the fact that the team Liu Zifen used a method with serious shortcomings for the measurement of “swinging” the light that came from the accretion disk of a black hole — hot, thin, rotating disk formed by matter that spirals slowly into the center of the object.
What Liu and his team interpreted as the light emitted by a black hole, actually a light overheated gas from the companion star, which absorbs a black hole. After the “line absorption” companion star has been removed from the observations of “impossible” a massive black hole, the fluctuations of light suddenly stopped, which led scientists to the conclusion that the mass of an object is not more than 20 solar masses. Although none of the three documents has not yet passed peer review, the authors of the studies came to the same conclusion, using different methods of data interpretation, which in itself is quite telling. Despite the fact that with 100% certainty say that the object in the system LB-1 — a normal black hole is impossible, most likely, the Chinese astronomers did wrong. And this once again proves that Einstein’s General relativity best describes our world.
