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 LickExpand
Ring Particle Composition and Size Distribution
We review recent progress concerning the composition and size distribution of the particles in Saturn's main ring system, and describe how these properties vary from place to place. We discuss howExpand
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
The Structure of Saturn's Rings
Our understanding of the structure of Saturn's rings has evolved steadily since their discovery by Galileo Galilei in 1610. With each advance in observations of the rings over the last fourExpand
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
Saturn's cloud structure and temporal evolution from ten years of Hubble Space Telescope images (1994 2003)
Abstract We present a study of the vertical structure of clouds and hazes in the upper atmosphere of Saturn's Southern Hemisphere during 1994–2003, about one third of a Saturn year, based on HubbleExpand
Saturn’s wayward shepherds: the peregrinations of Prometheus and Pandora
Abstract Saturn’s narrow F ring is flanked by two nearby small satellites, Prometheus and Pandora, discovered in Voyager images taken in 1980 and 1981 (Synnott et al., 1983 , Icarus 53, 156–158).Expand
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
Photometry of the Saturnian Satellites During Ring Plane Crossing
Abstract The first near-infrared (0.9 μm) photometric observations of Saturn's five medium-sized satellites were obtained during the August 1995 ring plane crossing with Palomar Observatory's 60-in.Expand
