How Magnetic Field Strength Affects Stellar Coronal Mass Ejection Dynamics

The 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

Reconfiguration of Mercury's Exosphere During Strong Space Weather Events

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Mercury is exposed to various space weathering processes, which alter the surface and cause emission of atoms and molecules into the exosphere. The exosphere thus allows remote insights into the surface composition and erosion processes, with the emission of refractory elements such as Ca and Mg typically being dominated by micrometeoroid ...

IMF By‐Controlled Dawn–Dusk and Hemispheric Asymmetries of Kelvin–Helmholtz Waves and Reconnection Geometry Under Negative Dipole Tilt

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Along with magnetic reconnection, Kelvin‐Helmholtz (KH) waves are the main mechanisms controlling the solar wind‐magnetosphere interaction, enabling plasma transport into the magnetosphere due to secondary reconnection, diffusion and wave‐particle interactions.

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

The 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

The 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 ...

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

The 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.

A New Understanding of the Formation Phases of Fast Coronal Mass Ejections and Their Role in Shock Formation and Particle Acceleration

The Astrophysical Journal
We uncover a new pattern in the formation of fast coronal mass ejections (CMEs), consisting of three phases: a rapid lateral expansion ( hyperinflation ) lasting

The Role of Magnetic Skeleton in Solar Flare Filaments Activity

The 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 ...

Multi-instrument observations and tracking of a coronal mass ejection front from low to middle corona

Journal of Space Weather and Space Climate
The shape and dynamics of coronal mass ejections (CMEs) vary significantly based on the instrument and wavelength used. This has led to significant debate about the proper definitions of CME/shock fronts, pile-up/compression regions, and core ...
