Cassini images of Saturn's small inner satellites (radii of less than ∼100 kilometers) have yielded their sizes, shapes, and in some cases, topographies and mean densities. This information and numerical N-body simulations of accretionary growth have provided clues to their internal structures and origins. The innermost ring-region satellites have likely grown to the maximum sizes possible by accreting material around a dense core about one-third to one-half the present size of the moon. The… 

The inner small satellites of Saturn: A variety of worlds

The recent formation of Saturn's moonlets from viscous spreading of the main rings

TLDR
A hybrid simulation is reported in which the viscous spreading of Saturn’s rings beyond the Roche limit (the distance beyond which the rings are gravitationally unstable) gives rise to the small moons.

The peculiar shapes of Saturn’s small inner moons as evidence of mergers of similar-sized moonlets

The Cassini spacecraft revealed the spectacular, highly irregular shapes of the small inner moons of Saturn1, ranging from the unique 'ravioli-like' forms of Pan and Atlas2,3 to the highly elongated

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.

Observations and Models of Accretion in Saturn's F Ring

Saturn's F ring is the solar system's principal natural laboratory for direct observation of accretion and disruption processes. Among the structures contained in its meager ~10 km radial width are

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.

An Evolving View of Saturn’s Dynamic Rings

TLDR
The understanding of Saturn’s rings is reviewed after nearly 6 years of observations by the Cassini spacecraft and it remains unclear whether the vigorous evolutionary processes to which the rings are subject imply a much younger age than that of the solar system.

Stochastic orbital migration of small bodies in Saturn’s rings

Many small moonlets, creating propeller structures, have been found in Saturn’s rings by the Cassini spacecraft. We stu dy the dynamical evolution of such 20-50m sized bodies which are embedded in

THE POPULATION OF PROPELLERS IN SATURN'S A RING

We present an extensive data set of ∼150 localized features from Cassini images of Saturn's A ring, a third of which are demonstrated to be persistent by their appearance in multiple images, and half

100-metre-diameter moonlets in Saturn's A ring from observations of 'propeller' structures

TLDR
The observation of four longitudinal double-streaks in an otherwise bland part of the mid-A ring is reported, infering that these ‘propeller’-shaped perturbations arise from the effects of embedded moonlets approximately 40 to 120 m in diameter.

Saturn's small satellites: Voyager imaging results

Voyagers 1 and 2 provided images of sufficient resolution for morphologic and photometric studies of Saturn's small satellites. These objects, all very difficult to observe from earth, orbit Saturn

Planetary Rings

Planetary rings are those strikingly flat and circular appendages embracing all the giant planets in the outer Solar System: Jupiter, Saturn, Uranus, and Neptune. Like their cousins, the spiral

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 our

Accretion in the Roche Zone: Coexistence of Rings and Ringmoons

Abstract Traditional accretion simulations predict rapid accumulation of ring debris into single satellites, while most theories of ring formation dismiss any accretion within the classical Roche

The Dynamics of Planetary Rings

The discovery of ring systems around Uranus and Jupiter, and the Pioneer and Voyager spacecraft observations of Saturn, have shown that planetary rings are both more common and more complex than

Self‐gravity wakes in Saturn's A ring measured by stellar occultations from Cassini

An azimuthal brightness asymmetry in Saturn's A ring is caused by ephemeral agglomerations that continually form under the mutual gravity of the ring particles only to be torn apart by Keplerian

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.

Saturn Ring Particles as Dynamic Ephemeral Bodies

Although Saturn's rings are within the Roche zone, the accretion of centimeter-sized particles into large aggregates many meters in diameter occurs readily, on a time scale of weeks. These aggregates
