Annual Review of Earth and Planetary Sciences, 1993
The rings in the solar system and the mathematical and physical approaches to understanding them are described. The variety of ring phenomena revealed in recent years from space and earth-based observations is emphasized. Ideas for the recent history of rings are examined in some detail.

Reviews of Geophysics, 1995
There is a rich phenomenology within the planetary rings surrounding the giant planets, most of it discovered by the Voyagers during their historic tours of t he outer solar system in the 1980s. In the last decade, there have been two detailed IUGG reviews of planetary rings.

1989
Theoretical models of planetary-ring dynamics are examined in a brief analytical review. The mathematical description of streamlines and streamline interactions is outlined; the redistribution of angular momentum due to collisions between particles is explained; and problems in the modeling of broad, narrow, and arc rings are discussed.

Planetary rings are found around all four giant planets of our solar sys- tem. These collisional and highly flattened disks exhibit a whole wealth of physical processes involving microscopic dust grains, as well as meter-sized boulders. These processes, together with ring composition, can help to understand better the for- mation and evolution of proto-

Occurrence of Planetary Rings with Shepherds
Celestial Mechanics and Dynamical Astronomy, 2001We consider the system of planetary rings with shepherds as a restricted three or four-body problem, neglecting interactions between ring particles. We show that the generic occurrence of rings for the case of rotating short-range potentials can be extended to the case of gravitational potentials.
