Data-driven Magnetohydrodynamic Simulation of the Initiation of a Coronal Mass Ejection with Multiple Stages
J. H. Guo, S. Poedts, B. Schmieder +8
Coronal mass ejections (CMEs) are the primary drivers of adverse space-weather events, yet their initiation and onset prediction remain insufficiently understood due to the complex…

The Birth of a Major Coronal Mass Ejection with Intricate Magnetic Structure from Multiple Active Regions
Jinhan Guo, Y. W. Ni, B. Schmieder +9
Coronal mass ejections (CMEs) are the eruptions of magnetised plasma from the Sun and are considered the main driver of adverse space weather events. Hence, undrstanding its format…
