Early Time Small-scale Structures in Hot Exoplanet Atmosphere Simulations

The Astrophysical Journal
We report on the critical influence of small-scale flow structures (e.g., fronts, vortices, and waves) that immediately arise in hot exoplanet atmosphere simulations initialized with a resting state.

Interactions of Sublimated Frost With Volcanic Plumes: Modeling Io's SO2 Atmosphere Using the DSMC Method

Journal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.
Abstract Io's tenuous atmosphere consists primarily of sulfur dioxide (SO2 ${\text{SO}}_{2}$) with observed column densities of approximately 1016−1017 $1{0}^{16}-1{0}^{17}$ cm−2 ${\text{cm}}^{-2}$. However, it remains uncertain whether the sublimation of SO2 ${\text{SO}}_{2}$ surface frost or volcanic outgassing is the primary source of the SO2 ...

Bridging the Atmospheric Circulations of Hot and Warm Giant Exoplanets

The Astrophysical Journal
We 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 ...

Weakening Tropical West Pacific Ascent Strength Reduces East Pacific Low Clouds via Lower Free‐Tropospheric Moisture Convergence

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 7, July 2026.
Abstract Low clouds (LC) are the largest source of uncertainty in the climate response to increased CO2 ${\text{CO}}_{2}$ in global climate models. This is due to the multitude of factors that affect their behavior and how these are characterized across models.

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

Exoplanet Atmospheres [PDF]

, 2010
At the dawn of the first discovery of exoplanets orbiting Sun-like stars in the mid-1990s, few believed that observations of exoplanet atmospheres would ever be possible.

Stellar Variability of Known Exoplanet Hosts Observed by TESS

, 2021
Characterizing an exoplanet requires knowledge of its host star’s intrinsic properties. The activity of a star can lend a unique perspective of how the star interacts with an exoplanet atmosphere and the ability to confirm an exoplanet’s place in a ...

Mercury's Eccentric Orbit as a Driver of Significant “Seasonal” Change in Upstream Solar Wind Forcing

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Mercury experiences the most intense and variable solar wind (SW) conditions in the solar system due to its close, eccentric orbit about the Sun. In addition to variation driven by coronal source and solar cycle, the SW arriving at Mercury varies periodically as the planet's heliocentric distance changes by over 50% per orbit.

Exoplanet Aeronomy: A Case Study of WASP-69 b’s Variable Thermosphere

The Astronomical Journal
Aeronomy, the study of Earth’s upper atmosphere and its interaction with the local space environment, has long traced changes in the thermospheres of Earth and other solar system planets to solar variability in the X-ray and extreme-ultraviolet ...
