Astronomers discovered a brand new class of black holes

The researchers proposed a new method of searching for black holes, which indicated the possibility of the existence of objects much smaller than any previously known.

Over the years, astronomers studied black holes, which are formed during the explosion of supernovae and have tremendous gravity, as well as neutron stars — less dense objects that remain after the death of stars, not much more than the sun.

After decades of observations of the universe, scientists learned that black holes are about 5-15 times more than the mass of the Sun, and neutron stars are often 2.1 times. Because if the star is 2.5 times heavier than the sun dies, it should collapse into a black hole. However, the window in the range between the most small famous black holes and the largest neutron stars confused many researchers, so astrophysics from the University of Ohio decided to solve this mystery.

The team began to study the data of the analysis of light spectra of 100,000 Milky Way Stars collected during the study of the Galactic Evolution of the Apache Point Observatory. The shift of wavelengths to the blue and red edge allows you to determine that the star rotates around the invisible object.

After the narrowing of the search to the potentially suitable 200 systems, the astronomers discovered the red giant, which rotates around something that is much less famous black holes, but more neutron stars. After additional calculations and reconciliation with the Gaia satellite data, they realized that they found a black hole with a small mass, which was about 3.3 times heavier than the sun.

In addition to the fact that researchers used a new search method, they potentially identified the first representative of a new class of black holes, which previously did not know.
