An accretion disk is a structure (often a circumstellar disk) formed by diffuse material in orbital motion around a massive central body. The central...

The protoplanetary disk may not be considered an accretion disk, while the two are similar. While they are similar, an accretion disk is hotter, and spins...

A circumstellar disc (or circumstellar disk) is a torus, pancake or ring-shaped accretion disk of matter composed of gas, dust, planetesimals, asteroids...
