Keplerian Disk

(disk whose motion follows Kepler's laws)

A Keplerian Disk is a disk of material that follows Kepler's laws of motion in conjunction with a central mass, which could be a Circumstellar Disk, or rings around a planet, both of which generally follow the laws for the most part. The motion of disks can also be affected by forces making portions of the disk diverge from normal Keplerian Orbit such as Radiation Pressure from the central star or pressure from heat in the disk material.
