Impact cratering history of the Saturnian satellites

Journal of Geophysical Research: Solid Earth, 1985
The impact crater flux history of the Saturnian system has been estimated based on observed crater density data from the satellite surfaces, cratering data for the terrestrial planets, and theory. The proposed cratering flux has an history similar to that for the inner solar system: an initial very high cratering rate which exponentially decayed during

Albedo and color maps of the Saturnian satellites

Icarus, 1990
The paper discusses the production of maps of the albedos and colors of Mimas, Enceladus, Tethys, Dione, and Rhea over the full range of their imaged surfaces. Voyager images were used to prepare maps of the normal reflectances and color ratios (0.58/0.41 micron) of these satelites.

The lens feature on the inner saturnian satellites

Icarus, 2014
Abstract We have modeled an electron precipitation pattern expected on Mimas, Tethys, and Dione, using two different approaches. In the first approach, we adapt a previously developed model to compute an integrated energy flux into the surfaces of Mimas, Tethys, and Dione. This is a guiding-center, bounce-averaged model.

Spectral properties of icy saturnian satellites derived from cassini data

2014 6th Workshop on Hyperspectral Image and Signal Processing: Evolution in Remote Sensing (WHISPERS), 2014
Cassini's Visual and Infrared Mapping Spectrometer (VIMS) offers the first spatially resolved hyperspectral data of the Saturnian satellites [1] allowing a detailed comparison of their spectral properties including their spatial distribution across the satellite's surface.

Modeling Issues Concerning Motion of the Saturnian Satellites

The Journal of the Astronautical Sciences, 1999
A study is performed to find the minimum-order model that can achieve an accuracy of 1 km in the dynamic propagation of the Saturnian satellites over a period of four years. The need for such an investigation has risen out of recent advances in the accuracy of orbit determination techniques that are to be used in the Cassini mission.

The libration of the saturnian satellite dione B

Icarus, 1981
Previously published positions of Dione B are combined with new observations reported in this paper to determine its motion. The data are fit to the analytic solution of Erdi (1978) to derive the parameters of the libratory motion. The satellite oscillates about the leading equilateral libration point (L4) of Dione with a period of 785.0 + or - 0.5 ...

A new Saturnian satellite near Dione's L4 point

Icarus, 1980
A new satellite of Saturn, discovered by Laques and Lecacheux, has been observed on a number of occasions and its orbit determined. It has a period of 2.73614 plus or minus 0.00006 days and occupies the leading Lagrangian point (L4) of Dione. A second object has been observed on one night which may be near the L5 point of Dione.

Voyager disk resolved photometry of the Saturnian satellites

Icarus, 1984
The scattering properties of the icy satellites of Saturn are studied. Scans of intensity along the photometric equator near opposition are analyzed, and disk-resolved measurements of intensity are fitted to simple photometric functions. Histograms of the albedo distribution across the satellite disks are constructed, and the geometric albedos are ...

An evolutionary framework for the Jovian and Saturnian satellites

Earth, Moon, and Planets, 1987
The position of the satellite within the protonebula, the influence of the parent planet, particularly the relative effects of tidal (gravitational) as opposed to radiogenic (internal) heat generating processes, as well as the type of ice, exert a control on the evolutionary histories of the Jovian and Saturnian satellites.
