A group of astronomers from the Chinese Academy of Sciences discovered the first convincing evidence of the existence of the black hole of the intermediate volume (IMBH) in the M15 shadow clusters. The research was published in the Journal of Science of the National Science Magazine (NSR).
The opening is based on the analysis of Star J0731+3717, thrown out of the cluster at a record speed of 550 km/s – this is five times faster than necessary to overcome the attractiveness of the galaxy.
Scientists have analyzed the data of Gaia and Lamost telescopes, tracking the trajectory of 1000 high -speed stars and 100 ball clusters.
The calculations show that for the acceleration J0731+3717 to 550 km/s, a object weighs several thousand sun, concentrated in the area under 1 astronomical unit (distance from the earth to the sun), is necessary. This does not include the accumulation of neutron stars – only a single black hole can create such an effect.
The black holes have an average mass (from 100 to 100 thousand solar blocks) are considered as the seeds of Muslims for extremely black holes, but until now their existence is still hypotheses.
Experts note that the J0731+3717 star was thrown 20 million years ago due to the interaction with IMBH – this is the first time when Hills (the destruction of the double hole system) was recorded in the shadow clusters.
This discovery supports the theory that super -developed black holes from intermediaries.
Previously, scientists have found a strange star flying in space at a high speed.
