X3: МОЛОДОЙ ЗВЕЗДНЫЙ ОБЪЕКТ БОЛЬШОЙ МАССЫ, ВБЛИЗИ СВЕРХМАССИВНОЙ ЧЕРНОЙ ДЫРЫ SGR A

To date, the proposed observation of young stellar objects in the Galactic center still raises the question of where and how these objects could have formed due to the violent vicinity of Sagittarius A* (Sgr A*). An international team of researchers under the leadership of Dr Florian Peißker at the University of Cologne's Institute of Astrophysics has discovered a very young star in its formation phase near the supermassive black hole Sgr A* at the centre of our Milky Way. The star is only several tens of thousands of years old, making it younger than humanity. It weight and size is fifteen times as heavy and ten times as big as our Sun. The special thing about baby star X3a is that theoretically it should not be able to exist so close to the supermassive black hole in the first place. However, the team believes that it formed in a dust cloud orbiting the giant black hole and sank to its current orbit only after it had formed.
