Modeling the thermodynamical conditions in the Uranian subnebula – Implications for regular satellite composition

, 2003
We study the thermodynamical conditions existing in the Uranian subnebula from which the regular satellites were presumably formed, assuming it was produced by an earth-sized body impact on proto-Uranus (Stevenson [CITE]; Slattery et al. [CITE]).

Cratering and Tectonic History of the Largest Uranian Satellite, Titania: New Insights Enabled by Image Reprocessing

The Planetary Science Journal
From 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 (>

Gravity and Radio Science Investigation at the Moons of Uranus to Reveal Subsurface Oceans and Characterize Interior Structures

Journal of Geophysical Research: Planets, Volume 130, Issue 4, April 2025.
Abstract The prospect that the five major moons of Uranus could host subsurface oceans makes them high‐priority targets for future exploration. Different techniques can be used to search for deep oceans in these objects. Here, we focus on ocean detection and characterization from measurements of the moons' response to the gravitational tides and ...

Crater morphology and morphometry on the Uranian satellites

, 1987
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.

Solar Wind Power Likely Governs Uranus' Thermosphere Temperature

Geophysical Research Letters, Volume 51, Issue 22, 28 November 2024.
Abstract Observations of Uranus in the near‐infrared by ground‐based telescopes from 1992 to 2018 have shown that the planet's upper atmosphere (thermosphere) steadily cooled from ∼700 to ∼450 K. We explain this cooling as due to the concurrent decline in the power of the solar wind incident on Uranus' magnetic field, which has dropped by ∼50% over the

High-technology Operation for Planetary Exploration - uRanian mOons impActoR (HOPE-ROAR) mission: an innovative in-depth study of the Uranian satellites

, 2023
Within our solar system, ice giants such as Uranus have long remained discarded for in-depth research with a dedicated spacecraft mission. Uranus has only been briefly visited by the Voyager 2 spacecraft, whose flybys occurred over 30 years ago.

The five largest satellites of Uranus: Astrometric observations spread over 29 years at the Pico dos Dias Observatory

, 2022
International audienceWe present the astrometry of the five largest satellites of Uranus from observations spread over almost three decades with photographic plates and CCDs (mainly), taken at the Pico dos Dias Observatory - Brazil.

The discovery of faint irregular satellites of Uranus

, 2004
We report the discovery of four new uranian irregular satellites in our deep, mR 3c25.4, optical search around that planet. The orbital properties of these satellites are diverse.

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.
