Statistical Scale Analyses of a Diurnal Periodicity in Auroral Kilometric Radiation, Observed by Wind/WAVES

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract The Earth's strongest natural radio emission is Auroral Kilometric Radiation (AKR), which is correlated with auroral intensity, and is a barometer for space weather. AKR is generated by the electron cyclotron maser instability, with sources on auroral field lines. Previous work on AKR and radio emissions from other planets (or stars) points to

Seasonal Changes in the Atmosphere of HD 80606 b Observed with JWST’s NIRSpec/G395H

The Astronomical Journal
High-eccentricity gas giant planets serve as unique laboratories for studying the thermal and chemical properties of H/He-dominated atmospheres. One of the most extreme cases is HD 80606 b—a hot Jupiter orbiting a Sun-like star with an eccentricity of 0 ...

Inferring Io's Internal Properties by Combining Gravity Measurements and Volcanic Activity

Journal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.
Abstract With its extreme geological activity, Io represents an archetype for tidally heated exoplanets/moons and provides insight into early stages of terrestrial planet evolution. Decades of ground‐based observations and multiple space missions have refined our understanding of Io, yet it remains debated where inside Io the tidal heating takes place.

Bistability, Oscillations, and Multistability on Hycean Planets

The Astrophysical Journal
Hycean planets are hypothetical exoplanets characterized by H _2 O oceans and H _2 -rich atmospheres. These planets are high-priority targets for biosignature searches, as they combine abundant surface liquid water with easy-to-characterize H _2 -rich ...

The ORCA‐TWIN qCMOS Experiment I. Science Case and Commissioning at Calar Alto Observatory

Astronomische Nachrichten, Volume 347, Issue 7, August 2026.
ABSTRACT We describe a pilot study to explore a new generation of fast and low noise CMOS image sensors for time domain astronomy, using two remote telescopes with a baseline of 1635 km. The experiment involves direct imaging with novel qCMOS image sensor technology that combines fast readout with sub‐electron readout noise.

The Spin Zone: Synchronously and Asynchronously Rotating Land Planets Have Spectral Differences in Transmission

The Planetary Science Journal
New observational facilities are beginning to enable insights into the three-dimensional (3D) nature of exoplanets. Transmission spectroscopy is the most widely used method for characterizing transiting temperate exoplanet atmospheres, but because it ...

A Theory for the Global Wind Energy Dissipation Across Climates

AGU Advances, Volume 7, Issue 5, August 2026.
Abstract Atmospheric winds play a key role in shaping climate, ecosystems, and infrastructure. The energy that drives the winds is generated by the atmospheric heat engine. However, traditional entropy‐budget descriptions of this heat engine rely on poorly constrained microscale processes, limiting their predictive power.

Global dust model intercomparison in AeroCom phase I [PDF]

, 2011
This study presents the results of a broad intercomparison of a total of 15 global aerosol models within the AeroCom project. Each model is compared to observations related to desert dust aerosols, their direct radiative effect, and their impact on the ...
