An investigation of magnetic energy and helicity thresholds at the onset of solar eruptions based on numerical simulations
Xinkai Bian, Chaowei Jiang, Qingjun Liu +5
Identifying universal, topology-independent thresholds in the coronal magnetic fields at onset of solar eruptions is crucial for physics-based prediction of eruptions. To this end,…
Modeling of Coronal Mass Ejection Originated from a Sheared Arcade of Realistic Active-Region Scale and Its Propagation in the Heliosphere: Methodology
Chaowei Jiang, Xueshang Feng, Liping Yang +4
Simulating coronal mass ejections (CMEs) from their origin in active regions (ARs) to their propagation to Earth remains challenging, particularly when aiming to resolve AR scales…
The role of photospheric magnetic flux diffusion in initiation of solar eruptions
Xinkai Bian, Chaowei Jiang, Yang Wang +4
Solar eruptions may occur at different evolutionary stages of active regions, during which the photospheric motions manifest in various forms, including flux emergence, sunspot rot…
MHD Modeling of the Near-Sun Evolution of Coronal Mass Ejection Initiated from a Sheared Arcade
Jinnan Cai, Ling Zhang, Chaowei Jiang +4
Coronal mass ejections (CMEs) are phenomena in which the Sun suddenly releases a mass of energy and magnetized plasma, potentially leading to adverse space weather. Numerical simul…
