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.

Altitude Profile and Isotopic Composition for N2 From Pioneer Venus Mass Spectra
Geophysical Research Letters, Volume 52, Issue 23, 16 December 2025.Abstract We report the highest resolution altitude profile and isotopic composition for N2 at Venus, to date. These results were obtained through re‐analysis of data acquired by the Pioneer Venus Large Probe Neutral Mass Spectrometer (LNMS). The N2 is non‐uniformly mixed across the clouds and sub‐cloud atmosphere (∼59–15 km) yet uniformly mixed across ...

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 ...

Earth and Space Science, Volume 12, Issue 12, December 2025.Abstract Earth's radiation belts are the regions where highly energetic charged particles are trapped by Earth's magnetic field, posing significant risks to the satellites and other space‐based technologies. Understanding the dynamics of the radiation belts is critical not only for advancing fundamental plasma physics but also for predicting and ...

Early Time Small-scale Structures in Hot Exoplanet Atmosphere Simulations
The Astrophysical JournalWe report on the critical influence of small-scale flow structures (e.g., fronts, vortices, and waves) that immediately arise in hot exoplanet atmosphere simulations initialized with a resting state.

Importance of Sample Selection in Exoplanet-atmosphere Population Studies
The Astronomical Journal, 2022 Understanding planet formation requires robust population studies, which are designed to reveal trends in planet properties. In this work we aim to determine if and how different methods for selecting populations of exoplanets for atmospheric ...

Radiation Transport Through the Martian Atmosphere as a Function of the Zenith Angle
Journal of Geophysical Research: Planets, Volume 130, Issue 12, December 2025.Abstract The topographic influence of the radiation environment on the Martian surface radiation is crucial for future human exploration. Topographic maps help assess radiation flux variations, aiding in hazard evaluation. Creating a global radiation map requires accounting for seasonally varying atmospheric density, heliospheric modulation, and ...

Evolution of Terrestrial Planetary Bodies and Implications for Habitability
Reviews of Geophysics, Volume 63, Issue 4, December 2025.Abstract The terrestrial planetary bodies of our solar system—Mercury, Venus, Earth, and Mars—share a common origin through nebular accretion and early magma ocean differentiation, yet they diverged significantly in geological evolution, tectonic regimes, and habitability.
