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

Is the Uranus Heat Flow Puzzling?
Geophysical Research LettersThe low internal heat flow of Uranus has been confirmed and determined for the first time. It may be representative of the average rather than a fluctuation due to the unusual seasonal or condensation cycles. The very different value for Neptune suggests

Asymmetry in Uranus' High Energy Proton Radiation Belt
Geophysical Research LettersUranus is one of the least explored planets in our solar system, it exhibits a unique magnetic field structure which was observed by NASA's Voyager 2 mission nearly 50 years ago.

Beam-axis stability during gantry rotation measured with scintillation dosimetry. [PDF]
J Appl Clin Med PhysAbstract Purpose Volumetric modulated arc therapy (VMAT) requires high mechanical precision due to continuous gantry rotation. This study aims to investigate beam‐axis stability during VMAT delivery and evaluate scintillation‐based imaging as a complementary quality assurance (QA) tool.

Does Uranus' Asymmetric Magnetic Field Produce a Relatively Weak Proton Radiation Belt?
Geophysical Research Letters, 2022 Since the Voyager 2 flyby in 1986 the radiation belts of Uranus have presented a problem for physicists. The observations indicate the electron radiation belt is far more intense than the proton radiation belt, and while the electron intensities are ...

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 ...
