Cupid is doomed: An analysis of the stability of the inner uranian satellites [PDF]
Icarus, 2012 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 system is unstable, resulting in the eventual crossing of orbits and probable subsequent collision of moons.

Spectral Trends across the Rings and Inner Moons of Uranus and Neptune from JWST NIRCam Images
The Planetary Science JournalJWST NIRCam images provide low-resolution spectra of the rings and inner moons orbiting Uranus and Neptune. These data reveal systematic variations in spectral parameters like the strength of the strong OH absorption band around 3 μ m and the spectral ...

Ariel’s Medial Grooves: Spreading Centers on a Candidate Ocean World
The Planetary Science JournalWe present evidence that Ariel's massive chasma-medial groove systems formed via spreading, where internally sourced material ascended and formed new crust.

Resonant chains and three-body resonances in the closely packed inner Uranian satellite system [PDF]
Monthly Notices of the Royal Astronomical Society, 2014 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 satellites. We find that the three-body Laplace angle values are distributed unevenly and have histograms showing structure, if the angle is associated with a resonant chain,

The Planetary Science JournalFrom heavily cratered Umbriel to extensively tectonized Miranda, Titania is an intermediary of the Uranian system: heavily cratered, yet tectonically modified. An outstanding mystery in Titania's crater population is its apparent relative lack of large (>

Crater morphology and morphometry on the Uranian satellites [PDF]
Fresh craters on the icy Uranian satellites exhibit a range of morphologies similar to craters on the icy satellites of Jupiter and Saturn. The general structural features found in the craters are described.

The Science Case for Spacecraft Exploration of the Uranian Satellites
, 2020 The five classical Uranian moons are possible ocean worlds that exhibit bizarre geologic landforms, hinting at recent surface-interior communication. However, Uranus' classical moons, as well as its ring moons and irregular satellites, remain poorly understood. We assert that a Flagship-class orbiter is needed to explore the Uranian satellites.

Dynamics of Enceladus and Dione inside the 2:1 Mean-Motion Resonance under Tidal Dissipation
, 2008 In a previous work (Callegari and Yokoyama 2007, Celest. Mech. Dyn. Astr. vol. 98), the main features of the motion of the pair Enceladus-Dione were analyzed in the frozen regime, i.e., without considering the tidal evolution.
