Images acquired of Saturn's rings and small moons by the Cassini Imaging Science Subsystem (ISS) during the first 9 months of Cassini operations at Saturn have produced many new findings. These include new saturnian moons; refined orbits of new and previously known moons; narrow diffuse rings in the F-ring region and embedded in gaps within the main rings; exceptionally fine-scale ring structure in moderate– to high–optical depth regions; new estimates for the masses of ring-region moons, as… Expand
Cassini Imaging Science: Initial Results on Saturn's Rings and Small Satellites
TLDR
Images acquired of Saturn's rings and small moons by the Cassini Imaging Science Subsystem have produced many new findings, including new saturnian moons; refined orbits of new and previously known moons; ring particle albedos in select ring regions; and never-before-seen phenomena within the rings.

Close-range remote sensing of Saturn’s rings during Cassini’s ring-grazing orbits and Grand Finale
TLDR
This work finds structures related to the detailed sculpting of rings by embedded masses, including structures near the moon Daphnis that have apparently experienced markedly different perturbations compared to the surrounding ring material, and complex structure elements within the largest propeller-shaped disturbances. Expand
High-resolution imaging of Saturn’s main rings during the Cassini Ring-Grazing Orbits and Grand Finale
In its two-part end-of-mission maneuvers, the Cassini has obtained and (as of this writing) continues to obtain the sharpest and highest-fidelity images ever taken of Saturn’s rings. Among theExpand
Structures induced by small moonlets in Saturn's rings: Implications for the Cassini Mission
[1] Particle simulations are carried out to study density features caused by small moonlets embedded in a dense planetary ring. The creation of a “propeller” like structure is found together withExpand
Close Cassini flybys of Saturn’s ring moons Pan, Daphnis, Atlas, Pandora, and Epimetheus
TLDR
The results show that Saturn's rings are substantially younger than the planet itself and constrain models of their origin, and five small moons located close to Saturn’s rings have unusual morphologies, contain water ice, and have accreted ring material. Expand
Cassini-Huygens’ exploration of the Saturn system: 13 years of discovery
TLDR
The Cassini-Huygens mission to Saturn provided a close-up study of the gas giant planet, as well as its rings, moons, and magnetosphere, and results show that Saturn's rings are substantially younger than the planet itself and constrain models of their origin. Expand
Fine-Scale Structures in Saturn's Rings:\\Waves, Wakes and Ghosts
The Cassini mission provided wonderful tools to explore Saturn, its satellites and its rings system. The UVIS instrument allowed stellar occultation observations of structures in the rings with theExpand
Saturn's Small Inner Satellites: Clues to Their Origins
TLDR
Cassini images of Saturn's small inner satellites have yielded their sizes, shapes, and in some cases, topographies and mean densities, and numerical N-body simulations of accretionary growth have provided clues to their internal structures and origins. Expand
The Orbits of Saturn’s Small Satellites Derived from Combined Historic and Cassini Imaging Observations
We report on the orbits of the small, inner Saturnian satellites, either recovered or newly discovered in recent Cassini imaging observations. The orbits presented here reflect improvements over ourExpand
Saturn's dynamic D ring
The Cassini spacecraft has provided the first clear images of the D ring since the Voyager missions. These observations show that the structure of the D ring has undergone significant changes overExpand

New observations of Saturn's coorbital satellites
Abstract We present observations of the Saturnian coorbital satellites, Janus and Epimetheus, obtained with the Caltech Cassegrain infrared camera at the Palomar Hale telescope in July and AugustExpand
An Explanation for Neptune's Ring Arcs
TLDR
Analysis of Voyager data shows that a radial distortion with an amplitude of approximately 30 kilometers is traveling through the ring arcs, a perturbation attributable to the nearby satellite Galatea, and the arcs appear to be azimuthally confined by a resonant interaction with the same satellite.

Periodic features in Saturn's F ring: evidence for nearby moonlets
THE Voyager 1 and 2 spacecraft1,2 found that the F ring of Saturn contains a remarkable diversity of features, from kinks and clumps to the so-called braids, with typical longitudinal spacingsExpand
An Absolute Radius Scale for Saturn's Rings
Radio and stellar occultation observations of Saturn's rings made by the Voyager spacecraft are discussed. The data reveal systematic discrepancies of almost 10 km in some parts of the rings,Expand
The structure of Saturn's rings: Implications from the Voyager stellar occultation
The Voyager 2 photopolarimeter observed the star δ Scorpii as it was occulted by Saturn's rings, giving ∼ 100 m resolution in the radial direction across the entire ring system. Radial structure canExpand
Encounter with saturn: voyager 1 imaging science results.
TLDR
As Voyager 1 flew through the Saturn system it returned photographs revealing many new and surprising characteristics of this complicated community of bodies, including small inner satellites that interact gravitationally with one another and with the ring particles in ways not observed elsewhere in the solar system.

Radiative transfer modeling of Saturn's outer B ring
Abstract We have investigated the light scattering behavior of Saturn's outer B ring at the 0.49-μm wavelength of the Voyager imaging system's clear filter. We study four types of radial regions:Expand
Saturn's rings: Particle size distributions for thin layer models
Abstract The small physical thickness of Saturn's rings requires that radio occultation observations be interpreted using scattering models with limited amounts of multiple scatter. A new model inExpand
