Radiation forces on small particles in the solar system
Abstract We present a new and more accurate expression for the radiation pressure and Poynting-Robertson drag forces; it is more complete than previous ones, which considered only perfectly absorbingExpand

Cassini Observes the Active South Pole of Enceladus
Cassini has identified a geologically active province at the south pole of Saturn's moon Enceladus. In images acquired by the Imaging Science Subsystem (ISS), this region is circumscribed by a chainExpand

Cassini Imaging of Jupiter's Atmosphere, Satellites, and Rings
The Cassini Imaging Science Subsystem acquired about 26,000 images of the Jupiter system as the spacecraft encountered the giant planet en route to Saturn. We report findings on Jupiter's zonalExpand

Enceladus's measured physical libration requires a global subsurface ocean
Abstract Several planetary satellites apparently have subsurface seas that are of great interest for, among other reasons, their possible habitability. The geologically diverse saturnian satelliteExpand

Shapes of the saturnian icy satellites and their significance
The sizes and shapes of six icy saturnian satellites have been measured from Cassini Imaging Science Subsystem (ISS) data, employing limb coordinates and stereogrammetric control points. Mimas,Expand

Elementary derivation of the perturbation equations of celestial mechanics
The equations of celestial mechanics that govern the time rates of change of the orbital elements are completely derived using elementary dynamics, starting from only Newton’s equation and itsExpand

The astronomical theory of climatic change on Mars
Abstract We examine the response of Martian climate to changes in solar energy deposition caused by variations of the Martian orbit and obliquity. We systematically investigate the seasonal cycles ofExpand
