Magnetic Reconnection Governs the Entire Lifecycle of Solar Eruptive Magnetic Flux Rope
Xinkai Bian, Chaowei Jiang, Qingjun Liu +3
While magnetic flux ropes (MFRs) are widely accepted to exist prior to many solar eruptions, the physical mechanism responsible for triggering and subsequently driving their erupti…
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,…
Revisited for existence proof of optimal solution in Bernoulli free boundary problem using an energy-gap cost functional
Shiouhe Wang, Fang Shen, Yi Yang +1
Bernoulli free boundary problem is numerically solved via shape optimization that minimizes a cost functional subject to state problems constraints. In \cite{1}, an energy-gap cost…
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…
Lightweight Remote Sensing Scene Classification on Edge Devices via Knowledge Distillation and Early-exit
Yang Zhao, Shusheng Li, Xueshang Feng
As the development of lightweight deep learning algorithms, various deep neural network (DNN) models have been proposed for the remote sensing scene classification (RSSC) applicati…
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…
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…
