An imaging photopolarimeter aboard Pioneer 11, including a 2.5-centimeter telescope, was used for 2 weeks continuously in August and September 1979 for imaging, photometry, and polarimetry observations of Saturn, its rings, and Titan. A new ring of optical depth < 2 x 10–3 was discovered at 2.33 Saturn radii and is provisionally named the F ring; it is separated from the A ring by the provisionally named Pioneer division. A division between the B and C rings, a gap near the center of the… Expand
Photometry and Polarimetry of Saturn's Rings From Pioneer Saturn
We 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 componentExpand
Photopolarimetry from Voyager 2; Preliminary Results on Saturn, Titan, and the Rings
The Voyager 2 photopolarimeter was reprogrammed prior to the August 1981 Saturn encounter to perform orthogonal-polarization, two-color measurements on Saturn, Titan, and the rings, and multiple, very narrow strands of material were found in the Encke division and within the brightest single strand of the F ring.

Scientific results from the pioneer Saturn infrared radiometer
The Pioneer 11 Infrared Radiometer instrument made observations of Saturn and its rings in broadband channels centered at 20 and 45 μm and obtained whole-disk information on Titan. A planetaryExpand
Bimodality and the formation of Saturn's ring particles
The F ring appears to have an outer and an inner rim, with only the latter observed by the imaging photopolarimeter (IPP) on the Pioneer Saturn spacecraft. The inside of the G ring, near 2.49 R/subExpand
Spatially resolved absolute spectrophotometry of Saturn: 3390 to 8080 Å
Abstract Absolute spectrophotometry of four regions on the visible disk of Saturn (north and south polar regions, equatorial band, south “temperate” region) from 3390 to 8080 A is reported. SpectralExpand
The brightening of Saturn's F ring
Abstract Image photometry reveals that the F ring is approximately twice as bright during the Cassini tour as it was during the Voyager flybys of 1980 and 1981. It is also three times as wide and hasExpand
Pioneer Saturn Celestial Mechanics Experiment
New theoretical calculations for the Saturn interior are described which use the latest observational data, including Pioneer Saturn, and state-of-the-art physics for the internal composition. Expand
Saturn's dynamic D ring
The Cassini spacecraft has provided the first clear images of the D ring since the Voyager missions. These observations show that the structure of the D ring has undergone significant changes overExpand
Photometry of the unlit face of Saturn's rings
Abstract From our telescopic observations of Saturn's rings in 1966, 1979, and 1980, the luminance of the unlit face at λ = 0.58 μ m is derived as a function of the height B ′ of the Sun above theExpand
Temperatures and Optical Depths of Saturn's Rings and a Brightness Temperature for Titan
The Pioneer Saturn infrared radiometer viewed Saturn's rings at 20- and 45-µm wavelength under several conditions of illumination. The data are analyzed to infer radial locations of major ringExpand


Pioneer imaging photopolarimeter optical system.
The imaging photopolarimeter aboard the Pioneer 10 spacecraft en route to the vicinity of Jupiter is described, and some performance characteristics and preliminary flight results are presented. Expand

Saturn's rings. I. Optical thickness of rings A, B, D and structure of ring B
Abstract A photometric study of high-resolution (∼0″.3) plates of Saturn taken at the Lowell Observatory in 1943 and 1945 is presented. N-S scans were taken over both the planet and rings. The excessExpand
The Imaging Photopolarimeter Experiment on Pioneer 11
One of the highest resolution images obtained is presented here along with a comparison of a sample of the authors' photometric and polarimetric data with a simple model, which seem consistent with increased molecular scattering at high latitudes. Expand
Photometric confirmation of the Encke division in Saturn's ring A
APPROXIMATELY once every 15 yr, it is possible to observe Saturn's satellite lapetus passing through the shadow of the rings. Observations of such events are of great value to studies of the opticalExpand
On a suspected ring external to the visible rings of Saturn
Abstract Reexamination of a photograph of Saturn taken on 15 November 1966, when the earth was nearly in the ring plane, indicates that ring material may exist outside the visible rings, extending toExpand
Trapped Radiation Belts of Saturn: First Look
The discovery of a new ring, called the F ring, a new division, the Pioneer division, and a moon, called 1979 S 2, is confirmed and Cosmic-ray albedo neutron decay should be looked into as a source of energetic particles in the inner magnetosphere of Saturn. Expand
Photometry and polarimetry of Jupiter at large phase angles: I. Analysis of imaging data of a prominent belt and a zone from pioneer 10
Limb-darkening curves are derived from Pioneer 10 imaging data for Jupiter's STrZ (−18 to −21° latitude) and SEBn (−5 to −8° latitude) in red and blue light at phase angles of 12, 23, 34, 109, 120,Expand
Saturnian Trapped Radiation and Its Absorption by Satellites and Rings: The First Results from Pioneer 11
The inner Saturn magnetosphere, because of its near-axial symmetry and the many discrete radiation absorption regions, offers a unique opportunity to study the acceleration and transport of charged particles in a planetary magnetic field. Expand
Saturn's ring and nearby faint satellites
Abstract Observations of Saturn's rings during passage of the Earth through the ring plane, coupled with those of others, suggest a ring thickness of 1.3 ± 0.3 km. The wide disparity in the opticalExpand
