decretion disk

(disk around an astronomical body of its ejected material)

A decretion disk is material around a star or other massive astronomical body distributed in the shape of a disk centered on the body, consisting of material ejected by the body. In effect, it is the inverse of an accretion disk. The ejected material of Be stars is thought to form decretion disks.
