Abstract: | Recent spacecraft observations of the Saturnian and Jovian ring systems have highlighted a plethora of interesting new phenomena
associated with those regions containing fine (micron and sub-micron sized) dust. Recognizing that these dust grains, by virtue
of being immersed within the planetary magnetospheres, are electrostatically charged to the point that they experience comparable
gravitational and electric forces, a new “gravito-electrodynamic” theory has been developed to describe their dynamics. This
theory has been successful in explaining all these phenomena in a systematic way. In this review, the basic model and its
range of validity are outlined, and its application to the Saturnian and Jovian ring systems are discussed. |
