Constraining Ocean and Ice Shell Thickness on Miranda from Surface Geological Structures and Stress Modeling

The Planetary Science Journal
Images from the Voyager 2 mission revealed the small Uranian satellite Miranda to be a complex, dynamic world. This is exemplified by signs of recent geological activity, including an extensive fault system and the mysterious coronae.

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;

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.

Voyager radio occultation by the Uranian rings: Structure, dynamics, and particle sizes [PDF]

, 1990
Diffraction of Voyager 2's 3.6 and 13 cm wavelength microwaves by the Uranian rings is removed through an inverse Fresnel transform filtering procedure that accommodates the significant eccentricity of the rings. Resulting 50 m resolution profiles at two

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 ...

A ring system detected around the Centaur (10199) Chariklo [PDF]

, 2014
Hitherto, rings have been found exclusively around the four giant planets in the Solar System1. Rings are natural laboratories in which to study dynamical processes analogous to those that take place during the formation of planetary systems and galaxies.

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

Titania’s Deuterium Abundance and the Origin of Its Water

The Planetary Science Journal
Models of our solar system’s protoplanetary disk account for processes such as the infall of water–ice-rich grains from the surrounding molecular cloud, the reprocessing of some infalling water–ice in the hot inner disk, and water’s outward migration in ...
