Cupid Is Not Doomed Yet: On the Stability of the Inner Moons of Uranus

Matija Ćuk, Robert S. French, Mark R. Showalter +2

Some of the small inner moons of Uranus have very closely-spaced orbits. Multiple numerical studies have found that the moons Cressida and Desdemona, within the Portia sub-group, a…

The science case for spacecraft exploration of the Uranian satellites: Candidate ocean worlds in an ice giant system

Richard J. Cartwright, Chloe B. Beddingfield, Tom A. Nordheim +15

The 27 satellites of Uranus are enigmatic, with dark surfaces coated by material that could be rich in organics. Voyager 2 imaged the southern hemispheres of Uranus' five largest '…

The Science Case for Spacecraft Exploration of the Uranian Satellites

Richard J. Cartwright, Chloe B. Beddingfield, Tom Nordheim +14

The five classical Uranian moons are possible ocean worlds that exhibit bizarre geologic landforms, hinting at recent surface-interior communication. However, Uranus' classical moo…

Orbits and resonances of the regular moons of Neptune

Marina Brozović, Mark R. Showalter, Robert A. Jacobson +3

We report integrated orbital fits for the inner regular moons of Neptune based on the most complete astrometric data set to date, with observations from Earth-based telescopes, Voy…

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…

Resonant Chains and Three-body Resonances in the Closely-Packed Inner Uranian Satellite System

Alice C. Quillen, Robert S. French

Numerical integrations of the closely-packed inner Uranian satellite system show that variations in semi-major axes can take place simultaneously between three or four consecutive…
