Effects of Planetary Parameters on Disequilibrium Chemistry in Irradiated Planetary Atmospheres: From Gas Giants to Sub-Neptunes

The Astrophysical Journal
A primary goal of characterizing exoplanet atmospheres is to constrain planetary bulk properties, such as their metallicity, C/O ratio, and intrinsic heat.

Earth-like Exoplanets in Spin–Orbit Resonances: Climate Dynamics, 3D Atmospheric Chemistry, and Observational Signatures

The Planetary Science Journal
Abstract Terrestrial exoplanets around M- and K-type stars are important targets for atmospheric characterization. Such planets are likely tidally locked with the order of spin–orbit resonances (SORs) depending on eccentricity. We explore the impact of SORs on 3D atmospheric dynamics and chemistry, employing a 3D coupled climate ...

State‐Dependence of Polar Amplification in an Idealized GCM

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Polar amplification (PA) is a robust feature of contemporary climate change, but its state‐dependence across different climate conditions is poorly understood despite potential relevance to paleoclimate records and future projections. Here we examine the state‐dependence of PA across a wide range of climate states in an idealized moist general

Observations of Exoplanet Atmospheres

, 2015
Detailed characterization of an extrasolar planet's atmosphere provides the best hope for distinguishing the makeup of its outer layers, and the only hope for understanding the interplay between initial composition, chemistry, dynamics & circulation, and

Thermoelastic Contraction as a Suppressor of Atmospheric Escape in Close-in Exoplanets

The Astrophysical Journal
The survival of volatile-rich atmospheres on close-in exoplanets challenges classical escape models. We identify a fully classical, interior-driven correction: thermoelastic contraction of the planetary mantle slightly increases the gravitational binding

A Cross‐Correlation Method to Evaluate Wind Retrieval Accuracy on Mars Using Simulated Microwave Limb Sounder Observations

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract While aspects such as the temperature and composition of the Martian atmosphere are relatively well known thanks to observations from numerous space missions, Martian atmospheric dynamics remain poorly constrained due to the scarcity of direct wind measurements. The use of microwave limb sounders to retrieve winds has been proposed in the past,

Radiative Transfer for Exoplanet Atmospheres

, 2017
Remote sensing of the atmospheres of distant worlds motivates a firm understanding of radiative transfer. In this review, we provide a pedagogical cookbook that describes the principal ingredients needed to perform a radiative transfer calculation and ...

Formation of Asteroid (16) Psyche by a Giant Impact

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract Asteroid (16) Psyche is the largest likely metal‐rich asteroid in the Solar System and the target of the NASA Psyche mission. The mission aims to determine whether the asteroid is the core of a differentiated planetesimal that lost its mantle via a giant impact.

Exoplanet Research with the Stratospheric Observatory for Infrared Astronomy (SOFIA)

, 2017
When the Stratospheric Observatory for Infrared Astronomy (SOFIA) was conceived and its first science cases defined, exoplanets had not been detected. Later studies, however, showed that optical and near-infrared photometric and spectrophotometric follow-
