Uranus’s and Neptune’s Stratospheric Water Abundance and Vertical Profile from Herschel-HIFI
The Planetary Science Journal, 2022 Here we present new constraints on Uranus’s and Neptune’s externally sourced stratospheric water abundance using disk-averaged observations of the 557 GHz emission line from Herschel’s Heterodyne Instrument for the Far-Infrared.

Evidence of a Polar Cyclone on Uranus From VLA Observations
Geophysical Research Letters, 2023 We present observations of Uranus in northern spring with the Very Large Array from 0.7 to 5 cm. These observations reveal details in thermal emission from Uranus' north pole at 10s of bars, including a dark collar near 80°N and a bright spot at the ...

Thermal and Tidal Evolution of Uranus with a Growing Frozen Core
The Planetary Science Journal, 2021 The origin of the very low luminosity of Uranus is unknown, as is the source of the internal tidal dissipation required by the orbits of the Uranian moons.

Pitch-angle diffusion coefficients from resonant interactions with electrostatic electron cyclotron harmonic waves in planetary magnetospheres [PDF]
Annales Geophysicae, 2011 Pitch-angle diffusion coefficients have been calculated for resonant interaction with electrostatic electron cyclotron harmonic (ECH) waves in the magnetospheres of Earth, Jupiter, Saturn, Uranus and Neptune.

Ice Giant Systems: The scientific potential of orbital missions to Uranus and Neptune
Planetary and Space Science, 2020 Uranus and Neptune, and their diverse satellite and ring systems, represent the least explored environments of our Solar System, and yet may provide the archetype for the most common outcome of planetary formation throughout our galaxy.

QUEST: A New Frontiers Uranus orbiter mission concept study
Acta Astronautica, 2020 The ice giant planets, Uranus and Neptune, are fundamentally different from the gas giant and terrestrial planets. Though ice giants represent the most common size of exoplanet and possess characteristics that challenge our understanding of the way our ...

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 18, 28 September 2026.Abstract The ability of convection‐permitting regional climate models to realistically simulate extratropical cyclones (ETCs) and associated near‐surface wind speeds and precipitation remains poorly documented. This study provides the first comprehensive evaluation of the sixth version of the Canadian regional climate model (CRCM) for this purpose over

Predictions of Auroral Electron Precipitation and Joule Heating at Uranus
Geophysical Research LettersThe precipitation of electrons and Joule heating are key processes through which energy is transferred from Uranus' magnetosphere to its upper atmosphere. These processes drive atmospheric ionization, thermospheric heating, and auroral emission at Uranus.
