Circumstellar Disk

A circumstellar disk is a torus, pancake or ring-shaped accumulation of matter composed of gas, dust, planetesimals, asteroids, or collision fragments in orbit around a star. These disks are formed by the process of accretion, which is the accumulation of particles from the surrounding space onto a central object. Circumstellar disks are important in the study of planet formation and are believed to be the birthplace of planets. They are also important in the study of stellar evolution, as they can provide clues about the history of a star and its planetary system. The study of circumstellar disks is an active area of research in astronomy and astrophysics.
