Strong Tidal Dissipation at Uranus?

The Planetary Science Journal, 2023
Geophysical estimates of paleo heat fluxes on the Uranian moons Miranda and Ariel are in the range of 25–75 mW m ^−2 . For a canonical Uranus dissipation factor Q = 18,000, expected equilibrium tidal heating rates for these satellites are less than 6 mW ...

Tropospheric Composition and Circulation of Uranus with ALMA and the VLA [PDF]

, 2020
We present Atacama Large Millimeter/submillimeter Array (ALMA) and Very Large Array (VLA) spatial maps of the Uranian atmosphere taken between 2015 and 2018 at wavelengths from 1.3 mm to 10 cm, probing pressures from ∼1 to ∼50 bar at spatial resolutions ...

New indication for a dichotomy in the interior structure of Uranus and Neptune from the application of modified shape and rotation data

, 2012
Since the Voyager fly-bys of Uranus and Neptune, improved gravity field data have been derived from long-term observations of the planets' satellite motions, and modified shape and solid-body rotation periods were suggested. A faster rotation period (-40

The Long‐Term C Footprint Trajectory and Emissions Attribution of a Large Boreal Reservoir (Paix Des Braves (Eastmain‐1), Québec)

Water Resources Research, Volume 62, Issue 2, February 2026.
Abstract Hydropower is considered essential in meeting the increasing demand in low carbon energy in the context of climate change. Greenhouse gas emissions (GHG) by hydroelectric reservoirs have nevertheless become a major concern to the energy sector.

Semi-Analytical Search for Sun-Synchronous and Planet Synchronous Orbits around Jupiter, Saturn, Uranus and Neptune

Mathematics, 2022
With the development of aerospace science and technology, more and more probes are expected to be deployed around extraterrestrial planets. In this paper, some special orbits around Jupiter, Saturn, Uranus, and Neptune are discussed and analyzed.

Selection of a common communication link geometry for Saturn, Uranus and Titan [PDF]

, 1974
Mission analysis link parametrics, considering a Pioneer baseline, are developed through launch energies, flyby radii, and trip time calculations. Projected is also a 1979 Jupiter Uranus opportunity for a derivative Mariner to fly to Uranus by using the ...

Dynamics of the giant planets of the solar system in the gaseous proto-planetary disk and relationship to the current orbital architecture [PDF]

, 2007
We study the orbital evolution of the 4 giant planets of our solar system in a gas disk. Our investigation extends the previous works by Masset and Snellgrove (2001) and Morbidelli and Crida (2007, MC07), which focussed on the dynamics of the Jupiter ...
