Corrugations and eccentric spirals in Saturn's D ring: New insights into what happened at Saturn in 1983
M. M. Hedman, J. A. Burns, M. R. Showalter
Previous investigations of Saturn's outer D ring (73,200-74,000 km from Saturn's center) identified periodic brightness variations whose radial wavenumber increased linearly over t…
Analysis of Clumps in Saturn's F Ring from Voyager and Cassini
Robert S. French, Shannon K. Hicks, Mark R. Showalter +2
Saturn's F ring is subject to dynamic structural changes over short periods. Among the observed phenomena are diffuse extended bright clumps (ECs) ~ 3-40 degrees in longitudinal ex…
Cupid is Doomed: An Analysis of the Stability of the Inner Uranian Satellites
Robert S. French, Mark R. Showalter
We have explored the stability of the inner Uranian satellites using simulations based on the most recent observational data. We find that, across a wide range of mass assumptions,…
The Brightening of Saturn's F Ring
Robert S. French, Mark R. Showalter, Rafael Sfair +5
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 wi…
Observing Planetary Rings with JWST: Science Justification and Observation Requirements
Matthew S. Tiscareno, Mark R. Showalter, Richard G. French +10
The James Webb Space Telescope (JWST) will provide unprecedented opportunities to observe the rings and small satellites in our solar system, accomplishing three primary objectives…
Non-circular features in Saturn's D ring: D68
M. M. Hedman, J. A. Burt, J. A. Burns +1
D68 is a narrow ringlet located only 67,627 km (1.12 planetary radii) from Saturn's spin axis. Images of this ringlet obtained by the Cassini spacecraft reveal that this ringlet ex…
