How Magnetic Field Strength Affects Stellar Coronal Mass Ejection Dynamics

open access: yesThe Astrophysical Journal
Observations show that stellar coronal mass ejection (CME) candidates display relatively lower kinetic energies compared to expectations from solar flare–CME relations extrapolated to the stellar regime. This behavior was predicted by studies of magnetic

Nanoscale space weathering features in mature lunar soil revealed by TEM and APT

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 8, Page 2048-2072, August 2026.
Abstract Space weathering significantly alters the optical, chemical, and structural properties of lunar regolith at micro‐ and nanoscales; yet detailed nanoscale variability within individual soils remains underexplored. Here we apply transmission electron microscopy (TEM) and atom probe tomography to four mineral grains (olivine, ilmenite, and two ...

Prediabetic cardiomyopathy is attenuated by hypothalamic PVN oxytocin neuron activation

open access: yesThe Journal of Physiology, Volume 604, Issue 16, Page 6872-6894, 15 August 2026.
Abstract figure legend A long‐term high‐fat, high‐fructose diet induces prediabetes with insulin resistance, hyperinsulinaemia, elevated triglycerides and metabolic‐associated steatotic liver disease (MASLD) in male rats. Animals developed prediabetic cardiomyopathy characterized by diastolic dysfunction, interstitial fibrosis and tachycardia ...

Ultra‐Low‐L Sub‐MeV Electron Microbursts During the May 2024 Super Storm

open access: yesGeophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract During the May 2024 super storm, we identified sub‐second microburst‐type relativistic electron precipitation events at McIlwain's L∼2 $L\sim 2$ in low‐Earth orbit using the Gamma‐ray Burst Monitor (CGBM) onboard the CALorimetric Electron Telescope on the International Space Station.

SIP-IFVM: An Observation-based Magnetohydrodynamic Model of a Coronal Mass Ejection

open access: yesThe Astrophysical Journal Supplement Series
Currently, achieving a balance between computational efficiency, accuracy, and numerical stability in coronal mass ejection (CME) simulations, particularly in the sub-Alfvénic coronal region, remains a significant challenge.

Interaction between a Coronal Mass Ejection and Comet 67P/Churyumov–Gerasimenko

open access: yesThe Astrophysical Journal
The interaction between a coronal mass ejection (CME) and a comet has been observed several times by in situ observations from the Rosetta Plasma Consortium, which is designed to investigate the cometary magnetosphere of comet 67P/Churyumov–Gerasimenko ...

A probabilistic approach to the drag-based model

open access: yesJournal of Space Weather and Space Climate, 2018
The forecast of the time of arrival (ToA) of a coronal mass ejection (CME) to Earth is of critical importance for our high-technology society and for any future manned exploration of the Solar System. As critical as the forecast accuracy is the knowledge

Acceleration and Release of Solar Energetic Particles Associated with a Coronal Shock on 2021 September 28 Observed by Four Spacecraft

open access: yesThe Astrophysical Journal
The main driver of the acceleration of solar energetic particles (SEPs) is believed to be shocks driven by coronal mass ejections. Extreme-ultraviolet (EUV) waves are thought to be the propagating footprint of the shock on the solar surface.

The Role of Magnetic Skeleton in Solar Flare Filaments Activity

open access: yesThe Astrophysical Journal
We report an M9.3 flare and filaments activities from NOAA Active Region 11261 that are strongly modulated by the 3D magnetic skeleton. Magnetic field extrapolation from the vector magnetic field suggests complex magnetic connectivity and the existence ...

Multiple shocks generated by the 2024 May 14 coronal mass ejection

open access: yesAstronomy & Astrophysics
Context. A series of powerful solar flares and coronal mass ejections (CMEs) occurred between 10 and 14 May 2024. As these eruptions propagated through the corona, they generated multiple solar type II radio bursts, indicating the presence of shock waves.
