The Uranus System from Occultation Observations (1977-2006): Rings, Pole Direction, Gravity Field, and Masses of Cressida, Cordelia, and Ophelia
Richard G. French, Matthew M. Hedman, Philip D. Nicholson +2
From 31 Earth-based and three Voyager 2 occultations spanning 1977--2006, we determine the orbital elements of the nine main Uranian rings with typical RMS residuals of 0.2 -- 0.4…
The composition of Saturn's rings
Kelly E. Miller, Gianrico Filacchione, Jeffrey Cuzzi +12
The origin and evolution of Saturn's rings is critical to understanding the Saturnian system as a whole. Here, we discuss the physical and chemical composition of the rings, as a f…
Kronoseismology V: A Panoply of Waves in Saturn's C Ring Driven by High-Order Internal Planetary Oscillations
R. G. French, B. Bridges, M. M. Hedman +3
Saturn's rings act as a system of innumerable test particles that are remarkably sensitive to periodic disturbances in the planet's gravitational field. We identify 15 additional d…
Axisymmetric density waves in Saturn's rings
M. M. Hedman, P. D. Nicholson
Density waves in Saturn's rings are usually tightly wrapped spiral patterns generated by resonances with either Saturn's moons or structures inside the planet. However, between the…
Kronoseismology IV. Six previously unidentified waves in Saturn's middle C ring
M. M. Hedman, P. D. Nicholson, R. G. French
Recent studies of stellar occultations observed by the Visual and Infrared Mapping Spectrometer (VIMS) onboard the Cassini spacecraft have demonstrated that multiple spiral wave st…
More Kronoseismology with Saturn's rings
M. M. Hedman, P. D. Nicholson
In a previous paper (Hedman and Nicholson 2013), we developed tools that allowed us to confirm that several of the waves in Saturn's rings were likely generated by resonances with…
