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-

Confirmation of a Non‐Transiting Planet in the Habitable Zone of the Nearby M Dwarf L 98‐59

Astronomische Nachrichten, Volume 347, Issue 2, February 2026.
ABSTRACT Only 40 exoplanetary systems with five or more planets are currently known. These systems are crucial for our understanding of planet formation and planet‐planet interaction. The M dwarf L 98‐59 has previously been found to show evidence of five planets, three of which are transiting.

On the Dual Nature of Atmospheric Escape

The Astrophysical Journal
Planetary atmospheres cannot remain hydrostatic at all altitudes because they approach finite density at infinite radius, implying infinite mass. Classical treatments address this in two directions: either retain a hydrostatic structure while allowing ...

Radiative braking in the extended exosphere of GJ436b

, 2015
The recent detection of a giant exosphere surrounding the warm Neptune GJ436 b has shed new light on the evaporation of close-in planets, revealing that moderately irradiated, low-mass exoplanets could make exceptional targets for studying this mechanism

Bridging Clarity and Accuracy: A Simple Spectral Longwave Radiation Scheme for Idealized Climate Modeling

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 2, February 2026.
Abstract Parameterizing radiative transfer in climate models means navigating trade‐offs between physical accuracy and conceptual clarity. However, currently available schemes sit at the extremes of this spectrum: correlated‐k schemes are fast and accurate but rely on lookup tables which obscure the underlying physics and make such schemes difficult to

Fractal Aggregate Aerosols in the Virga Cloud Code. II. Exploring the Effects of Key Cloud Parameters in Warm Neptune, Hot Jupiter and Brown Dwarf Atmospheres

The Astrophysical Journal
Aerosols and clouds are expected to be ubiquitous in exoplanet and brown dwarf atmospheres, where they can have a significant impact on transmission and emission spectra.

Sustainable Water Systems in Space: A Review of Current Technologies and Future Prospects

Water Resources Research, Volume 62, Issue 2, February 2026.
Abstract Sustainable water management is a critical challenge in space exploration, where the limited availability of resources requires innovative approaches to ensure astronauts' survival on long‐duration missions. This narrative review explores the key technologies and methods involved in water recycling, in situ resource utilization (ISRU), and ...

Two-dimensional Models of Microphysical Clouds on Hot Jupiters. I. Cloud Properties

The Astrophysical Journal
We present a new two-dimensional, bin-scheme microphysical model of cloud formation in the atmospheres of hot Jupiters that includes the effects of longitudinal gas and cloud transport.

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

Mechanisms of Superrotation in Slowly Rotating and Tidally Locked Planets

The Planetary Science Journal
Superrotation is a common feature of quickly rotating gas giants (e.g., Jupiter), slowly rotating planetary bodies (e.g., Titan), and tidally locked planets.
