What confines the rings of Saturn?
Radwan Tajeddine, Philip D. Nicholson, Pierre-Yves Longaretti +2
The viscous spreading of planetary rings is believed to be counteracted by satellite torques, either through an individual resonance or through overlapping resonances. For the A ri…
True Polar Wander of Enceladus From Topographic Data
Radwan Tajeddine, Krista M. Soderlund, Peter C. Thomas +4
Many obsects in the solar system are suspected to have experience reorientation of their spin axes. As their rotation rates are slow and their shapes are nearly spherical, the form…
Dynamical phenomena at the inner edge of the Keeler gap
Radwan Tajeddine, Philip D. Nicholson, Matthew S. Tiscareno +3
We analyze several thousand Cassini ISS images in order to study the inner edge of the Keeler gap in Saturn's outer A ring. We find strong evidence for an m=32 perturbation with a…
New constraints on Saturn's interior from Cassini astrometric data
Valéry Lainey, Robert A. Jacobson, Radwan Tajeddine +15
Using astrometric observations spanning more than a century and including a large set of Cassini data, we determine Saturn's tidal parameters through their current effects on the o…
Enceladus's measured physical libration requires a global subsurface ocean
P. C. Thomas, R. Tajeddine, M. S. Tiscareno +5
Several planetary satellites apparently have subsurface seas that are of great interest for, among other reasons, their possible habitability. The geologically diverse Saturnian sa…
Cassini ISS Mutual Event Astrometry of the Mid-sized Saturnian Satellites 2005-2012
N. J. Cooper, C. D. Murray, V. Lainey +3
We present astrometric observations of the Saturnian satellites Mimas, Enceladus, Tethys, Dione and Rhea from Cassini Imaging Science Subsystem (ISS) narrow-angle camera (NAC) imag…
Phoebe's orbit from ground-based and space-based observations
Josselin Desmars, Shan-Na Li, Radwan Tajeddine +2
The ephemeris of Phoebe, the ninth satellite of Saturn, is not very accurate. Previous dynamical models were usually too simplified, the astrometry is heterogeneous and, the Saturn…
