Back Reaction of the Untwisting Solar Corona Scars Sunspots
Chen Xing, Xin Cheng, Guillaume Aulanier +1
The paper reports that untwisting of coronal loops after magnetic reconnection transfers twist back to the photosphere, creating enhanced currents that appear as growing sunspot sc…
Formation of a Magnetic Flux Rope Prior to the Eruption: Insight from a Radiative MHD Simulation of Active Region Emergence
Can Wang, Takaaki Yokoyama, Feng Chen +3
Magnetic flux ropes (MFRs) are fundamental magnetic structures in solar eruptions, whose formation is generally attributed to (1) the emergence of subsurface flux tubes or (2) flux…
Initiation Route of Coronal Mass Ejections: II. The Role of Filament Mass
Chen Xing, Xin Cheng, Guillaume Aulanier +1
The thorough understanding on the initiation of coronal mass ejections (CMEs), which is manifested as a slow rise of pre-eruptive structures before the impulsive ejection in kinema…
Investigating an Erupting Metric-decimetric Radio Depression and its Physical Origin
B. T. Wang, X. Cheng, J. Y. Yan +8
We present direct metric-decimetric radio imaging observations of a fascinating quiescent filament eruption on 2024 March 17 using data from the DAocheng Radio Telescope (DART), wi…
