Protoplanetary Disk
A protoplanetary disk is a rotating circumstellar disk of dense gas surrounding a young newly formed star (“Protoplanetary Disk”)
Circumstellar Disk- revolving around or surrounding a star.

How it is formed
Protoplanetary disks are formed by surrounding components of close binary systems with respect to temperature and size (“Binary System (astronomy)”).
Binary System – a star system consisting of two stars orbiting around their common center of mass. It consists of brown dwarfs, planets, galaxies and asteroids
