A Cross‐Correlation Method to Evaluate Wind Retrieval Accuracy on Mars Using Simulated Microwave Limb Sounder Observations

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract While aspects such as the temperature and composition of the Martian atmosphere are relatively well known thanks to observations from numerous space missions, Martian atmospheric dynamics remain poorly constrained due to the scarcity of direct wind measurements. The use of microwave limb sounders to retrieve winds has been proposed in the past,

The Formation of Ultra-short-period Planets under the Influence of the Nearby Planetary Companions

open access: yesThe Astrophysical Journal
Ultra-short-period (USP) planets, defined as those with orbital periods shorter than 1 day, provide valuable insights into planetary evolution under strong stellar tidal interactions.

Formation of Asteroid (16) Psyche by a Giant Impact

open access: yesJournal 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.

Highly Sensitive Adaptive Protection for EV‐Integrated Distribution Networks

open access: yesInternational Transactions on Electrical Energy Systems, Volume 2026, Issue 1, 2026.
Integrating electric vehicle (EV)‐charging infrastructure presents environmental advantages, particularly in curbing carbon emissions within the transport sector and promoting sustainable energy solutions. However, the ascending adoption of EVs transforms the operational dynamics of low‐voltage distribution networks by introducing bidirectional power ...

Classification of Planetary Motion around Super-Jupiters and Brown Dwarfs

open access: yesUniverse
We investigate the orbital dynamics of an exosystem consisting of a solar-mass host star, a transiting body, and an Earth-size exoplanet within the framework of the generalized three-body problem.

Cation Disorder of Mg2SiO4 ${\text{Mg}}_{\mathbf{2}}{\text{SiO}}_{\mathbf{4}}$ in Super‐Earth Mantles

open access: yesGeophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract Understanding the mineralogy of exoplanets is essential for unraveling their interior structures, dynamics, and evolution. For large super‐Earths, the post‐post spinel Mg2SiO4 ${\text{Mg}}_{2}{\text{SiO}}_{4}$, one of the major mantle phases, may undergo the order‐disorder transition (ODT) at high temperatures.

The Dynamics-Based Approach to Studying Terrestrial Exoplanets

open access: yes, 2007
One of the great quests of astronomy is to obtain the spectrum of a terrestrial planet orbiting within the habitable zone of its star, and the dominant challenge in doing so is to isolate the light of the planet from that of the star. Dynamics-based methods separate these signals temporally, whereas imaging techniques do so spatially.
