Prometheus Induced Vorticity in Saturn's F Ring

Sutton, Phil J.; Kusmartsev, Feo V.

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 and dynamic place in the rings, probably in the whole Solar System, is the F ring. A highly disrupted ring with large asymmetries both radially and azimu…

The Atmospheres of Saturn and Titan in the Near-Infrared First Results of Cassini/vims

Sotin, C.; Brown, R. H.; Baines, K. H. +21 more

The wide spectral coverage and extensive spatial, temporal, and phase-angle mapping capabilities of the Visual Infrared Mapping Spectrometer (VIMS) onboard the Cassini-Huygens Orbiter are producing fundamental new insights into the nature of the atmospheres of Saturn and Titan. For both bodies, VIMS maps over time and solar phase angles provide in…

Cassini CIRS Observations of a Roll-Off in Saturn Ring Spectra at Submillimeter Wavelengths

Edgington, S. G.; Spilker, L. J.; Pilorz, S. H. +4 more

The Cassini Composite Infrared Spectrometer (CIRS) spatially resolved Saturn's main rings in the far-infrared, measuring the spectrum from 20 to 400 wavenumbers (cm^‑1) (tens of microns to submillimeter wavelengths). We find a spectral roll-off below 50 cm^‑1 (200 µm) for each of the A, B and C rings. From these data we d…

Titan's Ground Reflectance Retrieval from Cassini-Vims Data Taken during the July 2ND, 2004 Fly-By at 2 AM UT

D'Aversa, E.; Orosei, R.; Coradini, A. +5 more

An attempt to evaluate the preliminary values of the Titan's surface albedo at 2 µm from the first Cassini-VIMS observations of the moon is presented. The methodology is based on the application of radiative transfer calculations and a microphysical model of the Titan atmosphere based on fractal aerosol. As a first guess, the surface has bee…
