Ensemble Model Using the Fokker–Planck Equation and Alfvénic Drift for Estimating Proton Flux in Solar Energetic Particle Events

open access: yesEarth and Space Science, Volume 12, Issue 7, July 2025.
Abstract Observations of solar energetic particles (SEPs) accelerated at collisionless shocks driven by coronal mass ejections (CMEs) highlight the importance of understanding proton transport in velocity space. In this study, we present an ensemble model based on the one‐dimensional Fokker–Planck equation to estimate proton flux from CME‐driven shocks

An Oceanic Plateau Induced Subduction Zone Jump From Proto‐ to Paleo‐Tethys in East Kunlun, Northern Tibetan Plateau

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 7, July 2025.
Abstract The relationship between the Proto‐Tethys and Paleo‐Tethys is still debated. Some researchers believe that the Paleo‐Tethys opened after the Proto‐Tethys closed, while others argue that they are the same ocean with two stages of subduction. We present field geology, geochemical, and geochronological data to support the latter interpretation ...

Eoarchean–Paleoproterozoic Tectonothermal History of the Acasta Gneiss Complex Constrained by Titanite and Apatite Petrochronology

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 7, July 2025.
Abstract Deciphering Earth's earliest geodynamic processes requires temporally constrained chemical and structural data from rare exposures of ancient rocks. One of the most well‐studied of these exposures is the Acasta Gneiss Complex (AGC) in the Northwest Territories, Canada, which contains the oldest known felsic rocks on Earth.

MHD Simulation Study on Quasi‐Steady Dawn‐Dusk Convection Electric Field in Earth's Magnetosphere

open access: yesJournal of Geophysical Research: Space Physics, Volume 130, Issue 7, July 2025.
Abstract We investigated the large‐scale, quasi‐steady magnetospheric electric field by using global magnetohydrodynamic (MHD) simulations. When a southward interplanetary magnetic field was imposed, a large‐scale, dawn‐dusk electric field appeared in the magnetosphere.

Solar Wind‐Magnetosphere Coupling Under Interim Steady Conditions

open access: yesJournal of Geophysical Research: Space Physics, Volume 130, Issue 7, July 2025.
Abstract Solar wind—magnetosphere coupling is an important driver of dynamics within the magnetosphere–ionosphere–thermosphere system, traditionally modeled using coupling functions. Most coupling functions assume the interaction is one‐directional, that the solar wind conditions determine the energy that is transferred into the magnetosphere.
