Statistics of Saturn Ring Occultations
2020We calculate the excess variance, excess skewness and excess kurtosis including the effects of cylindrical shadows, along with gaps, ghosts and clumps (all calculated for the granola bar model for rectangular clumps and gaps). The widths and separation of the clumps play an analogous role to the relative size of the particle shadows, δ ...

The origin of Saturn's narrow G ring has been unclear. We show that it contains a bright arc located 167,495.6 ± 1.3 km from Saturn's center. This longitudinally localized material is trapped in a 7:6 corotation eccentricity resonance with the satellite Mimas.

The article focuses on research on rings discovered larger than that of Saturn planet. Topics discussed include discovery of a gargantuan planetary ring system by astronomers that is some 200 times larger than Saturn ring, collaboration of professional and amateur astronomers to study the system in detail and models suggesting that rings harbor a Mars ...

Space Science Reviews, 1975
This paper reviews observations of the rings of Saturn at visual, infrared, and radio wavelengths. Critical assessments are made of attempts to derive the physical characteristics of the rings from these measurements. A discussion is also given of the origin and evolution of the rings.

Saturn's Rings: Identification of Water Frost
Science, 1970A recently published infrared spectrum of Saturn's rings resembles our laboratory spectra of water frosts. Furthermore, there are discrepancies between the ring spectrum and ammonia frost spectra in the 2- to 2.5-μ region. These discrepancies render unlikely a reported identification of ammonia frost in the ring spectrum.

Microwave brightness of Saturn's rings
Icarus, 1974Abstract It is shown that a lower limit exists on the microwave brightness of the rings of Saturn, if they are assumed to be composed of Mie scatterers of geological composition. The lower limit (about 15°K) is due to scattering of planetary microwave emission.

The Exospheric Systems of Saturn's Rings
Icarus, 1995Abstract Because of collisional interaction with interplanetary meteoroids, the ring system of Saturn is supposedly a major source of neutral gas cloud in the inner saturnian system. We consider some new features brought about by the asymmetric impact geometry of the ring-meteoroid interaction.

Dynamics of Saturn's Dense Rings
2009The Cassini mission to Saturn opened a new era in the research of planetary rings, bringing data in unprecedented detail, monitoring the structure and properties of Saturn's ring system. The question of ring dynamics is to identify and understand underlying physical processes and to connect them to the observations in terms of mathematical models and ...

Photometry and polarimetry of Saturn's rings from Pioneer Saturn
Journal of Geophysical Research: Space Physics, 1980We present a profile of the average normal optical depth for Saturn's rings between 1.22 and 2.35 Rs. In the A and B rings, horizontal inhomogeneities make these values deceptive. A thinner component of the B ring with optical depth less than 0.08 covers ½% to 4% of its surface area. In the A ring the more transparent component has optical depth τs >
