Saturn's main rings are composed predominantly of water-ice particles ranging between about 1 centimetre and 10 metres in radius. Above this size range, the number of particles drops sharply, according to the interpretation of spacecraft and stellar occultations. Other than the gap moons Pan and Daphnis (the provisional name of S/2005 S1), which have sizes of several kilometres, no individual bodies in the rings have been directly observed, and the population of ring particles larger than ten… Expand
Planetary science: Saturn's bared mini-moons
Propeller-shaped structures seem to reveal the presence of moonlets, about 100 metres in diameter, embedded in Saturn's rings, adding to the picture of how the rings formed and are evolving. Expand
A belt of moonlets in Saturn’s A ring
Embedded moonlets found in Saturn’s A ring are probably the remnants of a shattered ring-moon of Pan size or larger, locally contributing new material to the older ring, which supports the theory of catastrophic ring creation in a collisional cascade. Expand
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 halfExpand
Migration of a Moonlet in a Ring of Solid Particles: Theory and Application to Saturn's Propellers
Hundred-meter-sized objects have been identified by the Cassini spacecraft in Saturn's A ring through the so-called propeller features they create in the ring. These moonlets should migrate due toExpand
Saturn's Small Inner Satellites: Clues to Their Origins
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 determination of the structure of Saturn’s F ring by nearby moonlets
Direct evidence of moonlets embedded in the ring’s bright core is reported, and it is shown that most of the F ring‘s morphology results from the continual gravitational and collisional effects of small satellites, often combined with the perturbing effect of Prometheus. Expand
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 inExpand
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 areExpand
The motions of small moons through Saturn's rings provide excellent tests of radial migration models. In theory, torque exchange between these moons and ring particles leads to radial drift. WeExpand
Stellar occultations observed by the Cassini Ultraviolet Imaging Spectrograph reveal the presence of transparent holes a few meters to a few tens of meters in radial extent in otherwise opticallyExpand


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
A recent cometary origin for Saturn's rings?
Gravitational torques and erosion by micrometeoroids may cause rapid evolution of Saturn's rings, possibly suggesting formation of the rings within the last 108 years. Optically thin and/or narrowExpand
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
Expectations for Cassini observations of ring material with nearby moons
This paper describes N-body simulations of two regions of the saturnian ring system and examines what we might expect the Cassini orbiter to see in those areas. The first region is the edge of theExpand
Saturn's Rings II. Particle Sizes Inferred from Stellar Occultation Data
Abstract We derive power-law particle size distributions for each of Saturn's main ring regions, using observations of the 3 July 1989 stellar occultation of 28 Sgr from Palomar, McDonald, and LickExpand
Satellite “wakes” and the orbit of the Encke Gap moonlet
Abstract Quasiperiodic optical depth variations have been observed in the Voyager stellar (PPS) and radio occultation profiles near the Encke Gap of Saturn's rings, and have also been detected in oneExpand
Density patterns induced by small moonlets in Saturn's rings?
An extension of the model of the gravitational scattering by moonlets in planetary rings to collisional diffusion is presented. The resulting typical propeller-shaped structures bear the chance toExpand
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
The disruption of planetary satellites and the creation of planetary rings
Abstract The Voyager spacecraft discovered that small moons orbit within all four observed ring systems coincident with the discovery of narrow and dusty rings around Jupiter, Saturn, Uranus andExpand
Voyager Photometry of Saturn's A Ring
Abstract Saturn's A Ring samples a wide range of dynamical environments, from the relatively unperturbed, optically thick inner region to the outer part of the ring, which contains numerous densityExpand
