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.

Constraining the Effect of Convective Inhibition on the Thermal Evolution of Uranus and Neptune [PDF]
The Planetary Science Journal, 2021 The internal heat flows of both Uranus and Neptune remain major outstanding problems in planetary science. Uranus’s surprisingly cold effective temperature is inconsistent with adiabatic thermal evolution models, while Neptune’s substantial internal heat

Fast E-sail Uranus entry probe mission [PDF]
, 2014 The electric solar wind sail is a novel propellantless space propulsion concept. According to numerical estimates, the electric solar wind sail can produce a large total impulse per propulsion system mass.

Explaining the low luminosity of Uranus: a self-consistent thermal and structural evolution [PDF]
Astronomy & Astrophysics, 2019 The low luminosity of Uranus is a long-standing challenge in planetary science. Simple adiabatic models are inconsistent with the measured luminosity, which indicates that Uranus is non-adiabatic because it has thermal boundary layers and/or conductive ...

Convective storms and atmospheric vertical structure in Uranus and Neptune. [PDF]
Philos Trans A Math Phys Eng Sci, 2020 The ice giants Uranus and Neptune have hydrogen-based atmospheres with several constituents that condense in their cold upper atmospheres. A small number of bright cloud systems observed in both planets are good candidates for moist convective storms ...

Constraining the depth of the winds on Uranus and Neptune via Ohmic dissipation [PDF]
Monthly notices of the Royal Astronomical Society, 2020 Determining the depth of atmospheric winds in the outer planets of the Solar system is a key topic in planetary science. We provide constraints on these depths in Uranus and Neptune via the total induced Ohmic dissipation, due to the interaction of the

Synchronicity in Post‐Jungian Astrology: A Cosmological Quest [PDF]
J Anal PsycholAbstract Jung promoted the idea of synchronicity in 1928, in the context of discussing the Chinese way of thinking. From 1928 to 1951, Jung’s informal formulations led to more than one understanding of synchronicity. He even tried to apply synchronicity to an astrological experiment.

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.

A collisionless scenario for Uranus tilting
, 2010 The origin of the high inclination of Uranus' spin-axis (Uranus' obliquity) is one of the great unanswered questions about the Solar system. Giant planets are believed to form with nearly zero obliquity, and it has been shown that the present behaviour ...
