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…
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…
Data-driven MHD simulation of a sunspot rotating active region leading to solar eruption
Chaowei Jiang, Xueshang Feng, Xinkai Bian +8
Solar eruptions are the leading driver of space weather, and it is vital for space weather forecast to understand in what conditions the solar eruptions can be produced and how the…
