Since the time of the Voyager flybys of Saturn in 1980–1981, Saturn's eccentric F ring has been known to be accompanied on either side by faint strands of material. New Cassini observations show that these strands, initially interpreted as concentric ring segments, are in fact connected and form a single one-arm trailing spiral winding at least three times around Saturn. The spiral rotates around Saturn with the orbital motion of its constituent particles. This structure is likely the result of… 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
A survey of low-velocity collisional features in Saturn's F ring
Abstract Small (∼50 km scale), irregular features seen in Cassini images to be emanating from Saturn’s F ring have been termed mini-jets by Attree et al. (2012) . One particular mini-jet was trackedExpand
Non-circular features in Saturn’s D ring: D68
Abstract D68 is a narrow ringlet located only 67,627 km (1.12 planetary radii) from Saturn’s spin axis. Images of this ringlet obtained by the Cassini spacecraft reveal that this ringlet exhibitsExpand
An Evolving View of Saturn’s Dynamic Rings
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. Expand
Detection of Low-velocity Collisions in Saturn's F Ring
Jets of material extending several hundred kilometers from Saturn's F ring are thought to be caused by collisions at speeds of several tens of ms–1 between ~10 km diameter objects such as S/2004 S 6Expand
Gravitational Vortices And Clump Formation In Saturn's F ring During An Encounter With Prometheus
Taking into account gravitational interaction between particles and a multi-stranded F-ring structure it is shown that Prometheus' encounters create rotational flows, like atmospheric vortices and the self-gravity enhances the accelerated growth and size of moonlets. Expand
Prometheus Induced Vorticity in Saturn’s F Ring
Saturn’s rings are known to show remarkable real time variability in their structure. Many of which can be associated to interactions with nearby moons and moonlets. Possibly the most interesting andExpand
Saturn's Strangest Ring Becomes Curiouser and Curiouser
Results from the Cassini spacecraft reported by Charnoz et al. in the same issue that reveal the existence of spiral features in the F ring are discussed, revealing one possible mechanism for the formation of spiral rings centers on an object called S/2004 S6. 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
Physical collisions of moonlets and clumps with the Saturn's F-ring core
Abstract Since 2004, observations of Saturn's F-ring have revealed that the ring's core is surrounded by structures with radial scales of hundreds of kilometers, called “spirals” and “jets.”Expand


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
Periodic collisions between the moon Prometheus and Saturn's F ring
SATURN 's F ring, which lies 3,400 km beyond the edge of the main ring system, was discovered by the Pioneer 11 spacecraft1 in 1979. It is a narrow, eccentric ring which shows an unusual 'braided'Expand
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 theirExpand
A numerical study of Saturn's F-ring
Abstract We study the short-term effects of “shepherding” satellites on narrow rings, in the general case where all bodies move along eccentric orbits. We do this by following numerically a ring ofExpand
How Prometheus creates structure in Saturn's F ring
Numerical models show that as Prometheus recedes from its closest approach to the F ring, it draws out ring material; one orbital period later, this affected region has undergone keplerian shear and is visible as a channel, in excellent agreement with structures seen in the Cassini images. Expand
Disentangling Saturn's F Ring. I. Clump orbits and lifetimes
Abstract A comprehensive analysis of the Voyager images reveals the kinematics and lifetimes of clumps in the F Ring. At any given time, the ring has 2–3 major clumps, each several times brighterExpand
Saturn's F Ring: Kinematics and Particle Sizes from Stellar Occultation Studies
Abstract The occultation of GSC5249-01240 by Saturn's rings was observed in a spectrally resolved mode using the Faint Object Spectrograph on the Hubble Space Telescope. By combining these data withExpand
Cassini Imaging Science: Initial Results on Saturn's Rings and Small Satellites
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.
