Ultraviolet geometric albedo of Uranus [PDF]

, 1988
The purpose was to obtain ultraviolet flux measurements of Uranus before and after the January 1986 flyby past Uranus by Voyager. These measurements were used to determine absolute flux distributions in the wavelength range 1950 to 3200 A.

Interior and Gravity Field Models for Uranus Suggest a Mixed-composition Interior: Implications for the Uranus Orbiter and Probe

The Planetary Science Journal
The interior composition and structure of Uranus are ambiguous. It is unclear whether Uranus is composed of fully differentiated layers dominated by an icy mantle or has smooth compositional gradients.

Candidate Centaurs trapped in mean motion resonances with Uranus

, 2003
We investigated the dynamical evolution of Centaurs moving in the region of the giant planets. Perturbations from four major planets (Jupiter, Saturn, Uranus and Neptune) were included.

Steady Collapse of Uranus' Exosphere After 1998 to the Present Decade

Geophysical Research Letters
Uranus' thermospheric temperature decreased from ∼800K in 1986 to ∼450K in 2022 as determined from observations of H3+ and H2 infrared emissions. Spitzer 2007 lower atmosphere observations do not emulate this cooling trend. Here we show that the atomic H

Ab Initio Entropy Calculations of Water Predict the Interiors of Uranus and Neptune to Be 15%–30% Colder than Previous Models

The Astrophysical Journal
Ab initio free energy calculations are employed to derive the entropy of liquid and superionic water over a wide range of conditions in the interiors of Uranus and Neptune.
