We have carried out a comprehensive survey of the best Cassini ISS data of Saturn's main rings for the purpose of cataloguing all observed spiral density waves, spiral bending waves, and other radial and quasi-radial ring structure. Our survey has revealed a number of new features, including the first known resonant waves raised by Enceladus and Hy...

The inner small satellites of Saturn are morphologically distinct depending on their dynamical position.

Cassini images of Saturn’s C ring taken near equinox have revealed a previously unseen pattern of sinusoidal brightness variations extending from the inner edge of the C ring (74,500 km from Saturn center) all the way out to the ramp between the B and C rings (92,000 km from Saturn center). This pattern first became clearly visible in images taken ...
Saturn s rings are a perfect example of an astrophysical disk, exhibiting dynamical processes common to all disks and at all scales. Whereas they are observed since the XVIIth century, they are still poorly understood. What is their origin? What is their total mass? What is their lifetime? What is a ring particle? Is their accretion close to the ri...
