The Role of Planetary Rotation in Polar Cusp Localization

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Juno observations have revealed that Jupiter's polar cusps are displaced toward dusk and even the nightside, contradicting the Earth‐derived paradigm that is confined to narrower ranges near noon. These findings underscore the overlooked influence of planetary rotation on magnetospheric dynamics, exposing a critical gap in current theoretical ...

The Impact of the Sulfur Allotropes and Sulfur Hydrides on the Venus Cloud Chemistry

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Venus is home to vivid sulfur chemistry, with SO2 ${\text{SO}}_{2}$ as the major sulfur gas species and a global cloud layer between 47 and 70 km composed of H2SO4 ${\mathrm{H}}_{2}{\text{SO}}_{4}$ and H2 ${\mathrm{H}}_{2}$O. The chemistry in the clouds has been extensively studied with 1D models, but none is able to reproduce the three orders

Decadal-interdecadal climate variability over Antarctica and linkages to the Tropics : analysis of ice core, instrumental, and tropical proxy data [PDF]

, 2012
The Antarctic continent contains the majority of the global ice volume and plays an important role in a changing climate. The nature and causes of Antarctic climate variability are, however, poorly understood beyond interannual time scales due to the ...

Multiepoch Stability in the Rotational Modulation of the Planetary-mass Companion Ross 458C

The Astrophysical Journal Letters
Spectroscopic variability is detected in brown dwarfs across all spectral types, suggesting atmospheric patchiness in brown dwarf atmospheres. We present JWST/NIRSpec time series observations of the T8.0 planetary-mass companion Ross 458C.

A Disintegrating Rocky World Shrouded in Dust and Gas: Mid-infrared Observations of K2-22 b Using JWST

The Astrophysical Journal Letters
The disintegrating ultrashort period rocky exoplanet K2-22 b periodically emits dusty clouds in a dynamically chaotic process resulting in a variable transit depth from 0% to 1.3%.

The Effects of Kinematic Magnetohydrodynamics on the Atmospheric Circulation of Eccentric Hot Jupiters

The Astrophysical Journal
Hot Jupiters are typically considered to be tidally locked due to their short orbital periods. The extreme irradiation can result in atmospheric species becoming thermally ionized on the dayside, which then interact with the planet’s magnetic field by ...
