Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.Abstract Saturn's Kilometric Radiation (SKR) is a powerful non‐thermal radio auroral emission produced by the Cyclotron Maser Instability (CMI), which generates waves close to the local cyclotron frequency in a highly magnetized plasma from mildly relativistic electrons.

The Response of Planetary Atmospheres to the Impact of Icy Comets. II. Exo-Earth Analogs
The Astrophysical JournalThe orbital regime of a terrestrial planet plays a significant role in shaping its atmospheric dynamics, climate, and hence potential habitability. The orbit is also likely to play a role in shaping the response of a planetary atmosphere to the influx of

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.

Bridging the Atmospheric Circulations of Hot and Warm Giant Exoplanets
The Astrophysical JournalWe perform high-resolution atmospheric flow simulations of hot and warm giant exoplanets that are tidally locked. The modeled atmospheres are representative of those on KELT-11 b and WASP-39 b, which possess markedly different equilibrium temperatures ...

Massive Rocky Planets May Suppress Deep Melting
AGU Advances, Volume 7, Issue 4, August 2026.Abstract Melting properties of silicates are critical to understanding the thermal evolution of rocky planetary interiors. In the deep mantles of massive rocky planets, post‐post‐spinel Mg2SiO4 ${\text{Mg}}_{2}{\text{SiO}}_{4}$ is potentially one of the most abundant mineral phases, yet its melting behavior remains unconstrained. Here, we determine the

Exoplanet Atmospheric Studies At High Spectral Resolution
, 2020 The study of exoplanet atmospheres is essential to understand the formation, evolution and composition of exoplanets. When a planet pass between its host star and an observer, a fraction of the star-light is absorbed by its atmosphere, thus revealing its

The Astronomical Journal, 2023 We present high-resolution dayside thermal emission observations of the exoplanet WASP-18 b using IGRINS on Gemini South. We remove stellar and telluric signatures using standard algorithms, and we extract the planet signal via cross-correlation with ...

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.
