FastQSL 2: A Comprehensive Toolkit for Magnetic Connectivity Analysis
Jun Chen, Thomas Wiegelmann, Li Feng +2
We present a new version of FastQSL for locating quasi-separatrix layers (QSLs) -- regions characterized by strong magnetic connectivity gradients, preferential current buildup, an…
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…
First Time Observed M-Shaped Coronal Mass Ejection Associated with a Blowout Jet and an Extreme Ultraviolet Wave
Yu-Hu Miao, Lin-Hua Deng, Chao-Wei Jiang +8
The coronal blowout jet, extreme ultraviolet (EUV) wave and coronal mass ejection (CME) are common phenomena in the solar atmosphere. In this paper, we report the occurrence of an…
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…
FIVR-NLFFF: A fully-implicit viscous-relaxation code for nonlinear force-free magnetic field extrapolation of the solar corona
Zhenhua Liu, Chaowei Jiang
Magnetic field extrapolation from the solar photosphere to the corona plays an important role in solar physics research. In this work, we present a fully-implicit viscous-relaxatio…
