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 ...

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

The JWST weather report: Retrieving temperature variations, auroral heating, and static cloud coverage on SIMP-0136 [PDF]
Astronomy & AstrophysicsSIMP-0136 is a T2.5 brown dwarf whose young age ($200±50$ Myr) and low mass ($15±3$ M_̊m Jup) make it an ideal analogue for the directly imaged exoplanet population.

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 ...

The Astrophysical JournalHot Jupiters are typically considered to be tidally locked due to their short orbital periods. The extreme irradiation can result in atmospheric species becoming thermally ionized on the dayside, which then interact with the planet’s magnetic field by ...

Planet Earth in reflected and polarized light. III. Modeling and analysis of a decade-long catalog of Earthshine observations [PDF]
Astronomy & AstrophysicsEarthshine observations offer a unique opportunity to study Earth as an exoplanet seen from the Moon. As the Sun-Earth-Moon geometry changes, Earth can be observed as a spatially unresolved exoplanet at different phase angles, providing important context

A Search for Temporal Atmospheric Variability of Kepler Hot Jupiters
The Astronomical JournalWe perform a systematic search for atmospheric variability in short-period gas-giant planets (hot Jupiters) observed by the Kepler mission, by looking for temporal variability of their secondary eclipse depths.
