Around the accretion disk are relatively dense clouds of hot gas that could be responsible for the broad emission lines seen in Type 1 Seyferts.

Light curves of this type have been predicted for stars whose accretion is dominated by Rayleigh - Taylor instabilities at the boundary between their magnetosphere and inner circumstellar disk, or where magneto - rotational instabilities modulate the accretion rate from the inner disk.
