Circumplanetary Disc
A circumplanetary disk (or circumplanetary disc, short CPD) is a torus, pancake or ring-shaped accumulation of matter composed of gas, Cosmic dust, dust, planetesimals, asteroids or collision fragments in orbit around a planet. They are reservoirs of material out of which Natural satellite, moons (or exomoons or subsatellites) may form. Such a disk can manifest itself in various ways. In August 2018, astronomers reported the probable detection of a circumplanetary disk around CS Chamaeleontis B, CS Cha B. 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." In 2020 though, the parameters of CS Chamaeleontis B, CS Cha B were revised, making it an accreting red dwarf star, and making the disk circumstellar disk, circumstellar. Theory A giant planet will mainly form via Core-accretion theory, core accretion. In this scenario a core forms via the accretion of small solids. Once the ...
