Cryovolcanism on the icy satellites

, 1994
Evidence of past cryovolcanism is widespread and extremely varied on the icy satellites. Some cryovolcanic landscapes, notably on Triton, are similar to many silicate volcanic terrains, including what appear to be volcanic rifts, calderas and solidified ...

Shepherding of the Uranian rings. I. Kinematics [PDF]

, 1987
We identify several orbital resonances involving the newly discovered satellites, 1986U7 and 1986U8, and the Uranian rings. The most important resonances in eccentric rings are known as eccentric reson­ances and are generalizations of the more ...

Properties of the Irregular Satellite System around Uranus Inferred from K2, Herschel, and Spitzer Observations [PDF]

, 2017
In this paper, we present visible-range light curves of the irregular Uranian satellites Sycorax, Caliban, Prospero, Ferdinand, and Setebos taken with the Kepler Space Telescope over the course of the K2 mission.

Leveraging Ceres to Gain Insights into the Candidate Ocean Worlds of Umbriel and Oberon That Orbit Uranus

The Planetary Science Journal
Ceres, located in the asteroid belt, exhibits intriguing parallels with two of the large Uranian satellites: Umbriel and Oberon. These similarities include size, bulk compositions, and dominantly radiogenic internal heat sources.

Thermal Oxidation Reaction between NH3 and O3: Low-temperature Formation of an -bearing Salt

The Planetary Science Journal
NH _3 has long been predicted to be an important component of outer solar system bodies, yet detection of this compound suggests a low abundance or absence on many objects where it would be expected. Here, we demonstrate that a thermally driven oxidation

Informed Design of a Gravity Science Experiment for the Future Geophysical Investigation of the Uranian Moons

The Planetary Science Journal
The outer solar system beyond Saturn remains unexplored by dedicated orbital missions. With a launch window opening in 2029, the Uranus Orbiter and Probe (UOP) mission has been prioritized as a NASA Flagship mission for the next decade (2023–2032) to ...

A Search for Distant Satellites of Neptune

, 1998
The recent discovery of two distant satellites of Uranus suggests that there could be similar bodies orbiting Neptune. Previous surveys for distant satellites of Neptune have had relatively bright magnitude limits (BJ ≃ 20·5) and would have missed ...

Astrometry of satellites I to V of Uranus 1990-1991?

, 1997
. 139 CCD images of the Uranian satellite sys-tem taken with the Jacobus Kapteyn Telescope in 1990 and 1991 have been calibrated astrometrically with two WFC photographic plates taken on the same telescope in 1996. The numbers of images are: I Ariel 139;
