of Saturn's rings from HST observations
The two major factors contributing to the opposition brightening of Saturn’s rings are i) the intrinsic brightening of particles due to coherent backscattering and/or shadow-hiding on their surfaces,
The spectrum of a Saturn ring spoke from Cassini/VIMS
On 2008, July, the Cassini/VIMS spectrometer detected spokes on the Saturn's B ring for the first time. These are the first measurements of the complete reflectance spectrum of the spokes in a wide
Astrometry of Saturn’s Satellites from the Hubble Space Telescope WFPC2
Highly accurate astrometric positions of 14 of Saturn's satellites have been obtained from 444 Hubble Space Telescope images taken with the Wide Field Planetary Camera 2 (WFPC2) between 1996 and
Statistical Perspectives on the Study of the Ring Spokes of Saturn
At the beginning of the Cassini Extended mission, the VIMS spectrometer was able to collect the first images of spokes on the Saturn rings at wavelengths longer than 1.1 μm ([1]). Previous

Chapter 16 Diffuse Rings
In order to give context to Cassini’s findings about Saturn’s diffuse rings, this chapter first recalls the Voyager and telescopic observations prior to 2004. Cassini has investigated these faint
Spokes in Saturn's B Ring: Could Lightning be the Cause?
Spokes are narrow markings across Saturn's B ring, most likely caused by a cloud of micrometer-sized particles intermittently lofted from the larger boulders in the ring. They were observed by the
First ground observations of Saturn's spokes around 2009 equinox
Since 1980, only spacecraft or space telescope have been able to image spokes (intermittently appearing radial or elongated dark markings in Saturn’s B-ring) around the planet equinoxes. Amateur


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 density

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 Lick
Radiative transfer modeling of Saturn's outer B ring
Encounter with saturn: voyager 1 imaging science results.
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.
A Study of Saturn's Ring Phase Curves from HST Observations
Abstract Solar phase curves between 0.3° and 6.0° and color ratios at wavelengths λ=0.336 μm and λ=0.555 μm for Saturn's rings are presented using recent Hubble Space Telescope observations. We test
