The rings of Uranus are oriented edge-on to Earth in 2007 for the first time since their 1977 discovery. This event provides a rare opportunity to observe their dark (unlit) side, where dense rings darken to near invisibility, but faint rings become much brighter. We present a ground-based infrared image of the unlit side of the rings that shows that the system has changed dramatically since previous views. A broad cloud of faint material permeates the system but is not correlated with the well… 
Clump Detections and Limits on Moons in Jupiter's Ring System
TLDR
Two families of clumps in the main ring are revealed: one close pair and one cluster of three to five, very different from those of the few other clumpy rings known; the origin and nonrandom distribution remain unexplained, but resonant confinement by Metis may play a role.
Thermal Emission from the Uranian Ring System
The narrow main rings of Uranus are composed of almost exclusively centimeter- to meter-sized particles, with a very small or nonexistent dust component; however, the filling factor, composition,
The rings and small moons of Uranus and Neptune

TLDR
These systems are studied for the information they reveal about the properties, history and ongoing evolution of the planetary systems of which they are a part; as dynamical analogues for other astrophysical systems such as protoplanetary disks; and for the wealth of fascinating properties and origin scenarios that make them worthy of study in their own right.
Satellite and Ring Systems
After having studied the Earth’s Moon in Chap. 8, we now look at the moons of the other planets of the solar system. A quick look at the two moons of Mars is followed by a detailed examination of the
The Case for a New Frontiers–Class Uranus Orbiter: System Science at an Underexplored and Unique World with a Mid-scale Mission
Current knowledge of the Uranian system is limited to observations from the flyby of Voyager 2 and limited remote observations. However, Uranus remains a highly compelling scientific target due to
Circumplanetary Dust Populations
We summarize the current state of observations of circumplanetary dust populations, including both dilute and dense rings and tori around the giant planets, ejecta clouds engulfing airless moons, and
Magnetospheric Studies: A Requirement for Addressing Interdisciplinary Mysteries in the Ice Giant Systems
Uranus and Neptune are the least-explored planets in our Solar System. This paper summarizes mysteries about these incredibly intriguing planets and their environments spurred by our limited

The Second Ring-Moon System of Uranus: Discovery and Dynamics
TLDR
Deep exposures of Uranus taken with the Hubble Space Telescope reveal two small moons and two faint rings that constitute a densely packed, rapidly varying, and possibly unstable dynamical system.
New Dust Belts of Uranus: One Ring, Two Ring, Red Ring, Blue Ring
TLDR
Near-infrared observations of the recently discovered outer rings of Uranus are compared with Hubble Space Telescope results, and it is found that the inner ring, R/2003 U 2, is red, whereas the outer ring,R/ 2003 U 1, is very blue.
Voyager 2 in the Uranian System: Imaging Science Results
TLDR
Voyager 2 images of the southern hemisphere of Uranus indicate that submicrometersize haze particles and particles of a methane condensation cloud produce faint patterns in the atmosphere, and Voyager images confirm the extremely low albedo of the ring particles.

Observations of Saturn's Ring-Plane Crossings in August and November 1995
Observations of Saturn's ring system with the Hubble Space Telescope during the 10 August 1995 Earth crossing and the 17 to 21 November 1995 solar crossing indicate that the F ring dominates their
Stability of Neptune's ring arcs in question
Although all four of the gas-giant planets in the Solar System have ring systems, only Neptune exhibits ‘ring arcs’—stable clumps of dust that are discontinuous from each other. Two basic mechanisms
Comprehensive Photometry of the Rings and 16 Satellites of Uranus with the Hubble Space Telescope
Abstract Photometric properties of 4 rings and 16 satellites of Uranus are presented, based on 41 Hubble Space Telescope images taken in 1997. Up to 25 filters per object covered the wavelength range
