Scientific paper

The dynamics of an epicyclic vortex (epiton) immersed in a dust ring is investigated. Numerical calculations taking vortex self-gravitation into account show that the epiton is compressed in the dust flow and drifts along the radius toward the densest part of the ring, indicating the stability of the vortex position in the ring. It is shown that the epiton chain is formed as a result of the interaction of the self-gravitating vortices produced by dust particles of the ring.
