Answer:

A protoplanetary disk is  round rotating object which is made of dense gas. This surrounds the newly formed star, Herbig star and T tauri star.

It is also considered as a accreation because the remnants like gases and other materials fall from them on to the star.The extremely illuminating protoplanetary disk are known as the proplyds.
