Abstract
THE hypothesis that single runaway stars are released from close binaries in which the companion star explodes as a carbon detonation supernova and is totally disrupted1 is proposed here. This is contrary to the earlier belief2 that at the time of the explosion the more evolved star is the less massive so that the supernova explosion which leaves behind a relativistic star core does not disrupt the binary3 but accelerates it to a velocity of a few tens of km sā1 (ref. 4). The binary consisting of a normal OB star and an inactive compact star could be detected as a runaway till it shows itself as an X-ray source.
