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,…

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…

Current Helicity in Response to Coronal Mass Ejections
Zheng Sun, Ting Li, Xinkai Bian +3
Coronal mass ejections (CMEs), powerful solar eruptions with massive plasma ejected into the interplanetary space, are caused by the release of the magnetic free enengy stored in c…
