Circumplanetary disk around exoplanet PDS 70c (point-like source on the right side)
A circumplanetary disk (or circumplanetary disc, short CPD) is a torus, pancake or ring-shaped accumulation of matter composed of gas, dust, planetesimals, asteroids or collision fragments in orbit around a planet. They are reservoirs of material out of which moons (or exomoons or subsatellites) may form.[1] Such a disk can manifest itself in various ways.
In August 2018, astronomers reported the probable detection of a circumplanetary disk around CS Cha B.[2] The authors state that "The CS Cha system is the only system in which a circumplanetary disc is likely present as well as a resolved circumstellar disc."[3] In 2020 though, the parameters of CS Cha B were revised, making it an accreting red dwarf star, and making the disk circumstellar.[4]
