Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.Abstract Xenon (Xe) is a heavy noble gas with intriguing chemical properties, such as having several stable isotopes and the ability to form compounds under extreme conditions. Despite the predictions based on cosmochemical models that suggest xenon should be relatively abundant in planetary reservoirs, empirical data indicate a significant depletion ...

Seasonal Changes in the Atmosphere of HD 80606 b Observed with JWST’s NIRSpec/G395H
The Astronomical JournalHigh-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 ...

Modeling Wind‐Driven Waves on Other Planets: Applications to Mars, Titan, and Exoplanets
Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.Abstract Waves could exist on any planet with sustained winds and stable surface liquids. However, differences in atmospheres, liquids, and gravity confound efforts to extend Earth‐based empirical wave models to other planetary environments. We adapted a physics‐based numerical wave model to study how planetary conditions affect the growth of waves. We

Bistability, Oscillations, and Multistability on Hycean Planets
The Astrophysical JournalHycean 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 ...

, 2019 An exoplanet's habitability will depend strongly on the presence of liquid water. Flux and/or polarization measurements of starlight that is reflected by exoplanets could help to identify exo-oceans.

The Bochum Survey of the Southern Galactic Disk: III. Complete Data Release
Astronomische Nachrichten, Volume 347, Issue 3, March 2026.ABSTRACT The Southern Galactic Disk Survey (GDS) monitored a mosaic of 268 fields along a 6°$$ {6}^{{}^{\circ}} $$‐wide stripe in the southern Galactic disk with simultaneous observations in r′$$ {r}^{\prime } $$ and i′$$ {i}^{\prime } $$ (7m≲r′,i′≲18m$$ {7}^{\mathrm{m}}\lesssim {r}^{\prime },{i}^{\prime}\lesssim {18}^{\mathrm{m}} $$) from September ...
