Astronomers found that a black hole or a neutron star, rotating around the spiral around the star-companion, faced her core and led to a supernova outbreak. The first in the history of observing such a catastrophic event is reported in an article published in the SCIENCE journal.
Scientists conducted observations of the object VT 1210 + 4956, which emitted bright radio emission, as part of a long-term project VERY LARGE ARRAY SKY SURVEY (VLASS). It is known that radiation comes from the outskirts of a dwarf star-forming galaxy, located about 480 million light years from the Earth. In 2014, the instruments on the ISS recorded an outbreak of X-rays emanating from the radio source.
The data obtained allowed astronomers to reconstruct events. Initially, VT 1210 + 4956 was a couple of massive stars rotating close to each other. One of them had a greater mass than the other, and eventually broke out as a supernova, leaving behind either a black hole, or a super-concrete neutron star. This compact object gradually climbed to the second star, and about 300 years ago he entered the upper layers of the atmosphere of the shining. As a result of the interaction of the star gas began to be thrown out, forming a ring around both objects.
Black hole or neutron star snuck up to the core of the star-companion, violating the nuclear synthesis, holding the star from Collapse, as a result of which she flashed like a supernova. At the same time, the jet of the stellar material was released, which reached nearby speeds.
