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.

Effects of Hot Oxygen Corona on Ion Escape From Venus‐Like Planets
Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.Abstract Due to the lack of a significant planetary magnetic field, the upper atmospheres of Venus‐like planets interact directly with the stellar wind. Therefore, thermal atomic oxygen in the thermosphere and hot oxygen in the corona produced by non‐thermal processes in the upper atmosphere act as a source of ion pickup loss.

Asymmetry and Dynamical Constraints in Two-limbs Retrieval of WASP-39 b Inferring from JWST Data
The Astronomical JournalTransmission spectroscopy has provided unprecedented insight into the makeup of exoplanet atmospheres. A transmission spectrum contains contributions from a planet’s morning and evening limbs, which can differ in temperature, composition, and aerosol ...

Predicting Nitrogen Isotope Fractionation in Nitrate Deposition on Early Mars
Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.Abstract Noachian and early Hesperian Mars were likely warm and wet, with an atmosphere abundant in molecular nitrogen. The recent discovery of nitrate deposits in the Yellowknife Bay mudstones at Gale Crater confirm the existence of nitrogen oxides (NOX) on Noachian Mars. The processes responsible for the production of these nitrates would fractionate
