Thirty “scattering” double stars notice that they are in a gap outside the famous galaxy

Science

When two stars love each other (and are big enough and close enough in space), they can begin to stabilize. Astronomers call this star partner a binary star system when the sun collapses. They go around each other, collect their gasoline together and sometimes even come back together from the dead.

That’s a good thing – but it’s not always fun. Sometimes a member of a twin package can be punished for their partner’s toxic behavior. Take around 30 binary star systems recently discovered near a group of galaxies 62 million light years from Earth. According to a study published on May 2 in the “Astrophysical Journal” lonely couples were removed from their home galaxy when one member of the partnership suddenly slipped, exploded into a neutron star and produced a very strong explosion so they both sent binary partners in around caring for interstellar space.

“It’s like a guest who is asked to leave a party with a passionate friend,” said senior study author Xiangyu Jin from McGill University in Montreal. “The companion star in this situation retreats from the galaxy just because it is in orbit with a star which is a supernova.”

Jin and his colleagues found that Star was exiled while studying 15-year data from X-rays collected by the X-ray Observatory of NADA (a powerful X-ray telescope mounted on a satellite). The team in the cluster identified Fornax, a group of more than 50 galaxies known in the Fornax constellation (in English for “furnace”). Some emission models tell the story of a binary star system where partners in collapsing neutrons suck up a lot of gas and dust from their partner stars in orbital drives and then overheat to tens of millions of degrees.

These heat and heat discs can only be seen in X-rays, the researchers said, and about 30 of the open X-ray signals come from outside of any known galaxy. The team found that this lighting system might have several neutron stars and non-neutrons thrown out of their home galaxy when neutron stars become supernovae and collapse.

Thirty pairs of wild stars may look a lot, but there may be many others in the narrow sky that researchers have seen, the team wrote. The researchers found in 200 Fornax special X-ray sources, but many were too far away to finish.
