accretion disk

(disk around an astronomical body of material that is accreting)

An accretion disk is material around a star or other massive astronomical body distributed in the shape of a disk centered on the body, spiraling in toward the body, attracted by gravity. Accretion disks are associated with interacting binary stars, with protostars (protoplanetary disks often include accretion) and with black holes (black hole accretion disk or BHAD), including supermassive black holes.
