X-ray binary in night sky, artwork. Red dwarf star (left) and a collapsed star (right) seen from the rocky surface of a planet. The collapsed star, which could be a neutron star or a black hole, has an accretion disc of material falling towards it from the red dwarf star. The extreme energies involved mean that X-rays are being emitted from the accretion disc. The two stars form a binary system, and because of the X-rays and the low mass of the red dwarf star (about half the mass of the Sun), it is called a low-mass X-ray binary system. Neutron stars and black holes are super-dense forms of matter, containing the mass of a star in a volume a few kilometres across or less.
