Abstract: Fallback position The idea of ‘fallback’ in supernova explosions, where some of the explosion ejecta fail to escape, has been invoked to explain black-hole formation, the spin distribution of magnetars, and the origin of Earth-mass planets around pulsars. Until now there has been no direct evidence that the process occurs. But a cool dust disk around an isolated young X-ray pulsar, detected in data from NASA's Spitzer Space Telescope, may be the first supernova fallback disk to have been observed. By analogy with protoplanetary disks around ordinary stars, a passive debris disk like this around a neutron star could be a site of planet formation.
