Both <a href=\"https:\/\/phys.org\/tags\/black+holes\/\" rel=\"tag\" class=\"\">black holes<\/a> and <a href=\"https:\/\/phys.org\/tags\/neutron+stars\/\" rel=\"tag\" class=\"\">neutron stars<\/a> are created in supernova explosions and are very dense\u2014giving them a massive gravitational pull. This makes them capable of capturing the outer layers of the normal star that orbits around it in the binary system, seen as a rotating disk of matter (mimicking a whirlpool) around the black hole\/neutron star.<\/p>\n<p>According to theoretical calculations, these rotating disks should show a dynamic instability: about once an hour, the inner parts of the disk rapidly fall onto the black hole\/neutron star, after which these inner regions re-fill and the process repeats. Up to now, this violent and extreme process had only been directly observed once, in a black hole binary system. For the first time, it has now been seen in a neutron star binary system, called Swift J1858.6\u20130814. This discovery demonstrates that this instability is a general property of these disks (and not caused by the presence of a black hole).<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Researchers from the University of Oxford have contributed to a major international study which has captured a rare and fascinating space phenomenon: binary star systems.
