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,…

MHD simulations of the slow-rise phase of solar eruptions initiated from a sheared magnetic arcade
Qingjun Liu, Chaowei Jiang, Zhipeng Liu
Before solar eruptions, a short-term slow-rise phase is often observed, during which the pre-eruption structure ascends at speeds much greater than the photospheric motions but muc…

A New Approach of Data-driven Simulation and Its Application to Solar Active Region 12673
Zhi-Peng Liu, Chao-Wei Jiang, Xin-Kai Bian +3
The solar coronal magnetic field is a pivotal element in the study of eruptive phenomena, and understanding its dynamic evolution has long been a focal point in solar physics. Nume…
