Scientific paper

The stability of a viscous differentially rotating protoplanetary disk is examined. It is shown that, besides the negative diffusion instability discovered by Lin and Bodenheimer (1981) and Ward (1981), a quasi-secular instability occurs in the disk with a positive diffusion coefficient. Dissipative disk instabilities form a series of rings around the sun. Conditions under which the rings are localized on planetary orbits are defined.
