Observations by the Galileo spacecraft and the Keck telescope showed that Jupiter's outermost (gossamer) ring is actually two rings circumscribed by the orbits of the small satellites Amalthea and Thebe. The gossamer rings' unique morphology-especially the rectangular end profiles at the satellite's orbit and the enhanced intensities along the top and bottom edges of the rings-can be explained by collisional ejecta lost from the inclined satellites. The ejecta evolves inward under Poynting…

The Rings of Jupiter as Seen by the Electron and Proton Radiation Belt Model Salammbô
A modeling of the effect of the rings of Jupiter on trapped >3‐MeV electrons and protons is proposed. The effect is then added to the physical model Salammbô and discussed against in situ…
Formation of the Thebe Extension in the Ring System of Jupiter
Jupiter's tenuous dust ring system is embedded in the planet's inner magnetosphere, and—among other structures—contains a very tenuous protrusion called the Thebe extension. In an attempt to explain…
Small-Scale Structure in Saturn's Rings
The rings of Saturn are the largest and most complex in the Solar System. Decades of observation from ground- and space-based observatories and spacecraft missions have revealed the broad structure…
The Structure of Jupiter's Ring System as Revealed by the Galileo Imaging Experiment
The jovian ring system was observed during four orbits of Galileo's nominal mission, when 25 clear-filter images of the rings were taken at spatial resolutions of 23 to 134 km/pixel; the ring…

The vertical thickness of Jupiter's Europa gas torus from charged particle measurements
Measurements and modeling suggest the presence of a neutral gas torus collocated with the orbit of Jupiter's moon Europa. Here we use data from the CMS instrument that is part of the Energetic…
Dusty Rings and Circumplanetary Dust: Observations and Simple Physics
Each giant planet is encircled by planetary rings, usually composed of particles centimeters to meters in radius, but each system also contains regions where much smaller dust grains predominate.…
A tenuous dust ring of Jupiter formed by escaping ejecta from the Galilean satellites
[1] This paper focuses on the dust environment between the orbits of the Galilean moons of Jupiter. Recent discovery of dust clouds around the Galilean satellites formed by impact ejecta from…
Saturn's largest ring
TLDR
It is reported that Saturn has an enormous ring associated with its outer moon Phoebe, extending from at least 128RS to 207RS (Saturn’s radius RS is 60,330 km); Dynamical considerations argue that these ring particles span the Saturnian system from the main rings to the edges of interplanetary space.
The jovian rings : new results derived from Cassini , Galileo , Voyage and Earth-based observations
Cassini’s Imaging Science Subsystem (ISS) instrument took nearly 1200 images of the Jupiter ring system during the spacecraft’s 6-month encounter with Jupiter (Porco et al., 2003, Science 299,…

Discovery of Jupiter's ‘gossamer’ ring
TLDR
An additional ring is discovered, which is far fainter than either of the (already faint) components previously identified, extending to a radius of 210,000 km.

Abstract In this paper, we apply orbital perturbation theory to the circumplanetary motion of micrometer-sized dust grains subject to gravitational, electromagnetic, and radiation forces. We extend…
