An international team of astronomers have discovered a runaway star PG 1610+062, which was dispersed by the gravity of a black hole high-mass object, whose existence in the milky Way has long remained unconfirmed. About it reported in a press release on Phys.org.
The researchers conducted observations of the star using the Keck telescope (Hawaii) and measured its rotation speed, radial velocity, and identified its chemical composition. It turned out that PG 1610+062 is a young massive star, which flies at a speed sufficient to leave the milky Way.
According to the calculations, the reason for such a high speed was supposed to be a black hole of average weight. Previously it was assumed that the runaway stars occur when a supermassive black hole destroying the dual system. However, the trajectory of PG 1610+062 does not pass near the center of the galaxy, where is the supermassive black hole Sagittarius a*.
According to the predictions, black holes, the average mass must exist in young star clusters in spiral branches of the milky Way, however, until now, such objects were found. In addition, it remains a mystery as there are these heavenly bodies.
