Reconnection Jets Detected during the Footpoint Drift of a CME Flux Rope: New Signatures of Ongoing 3D Arcade-Flux Rope Reconnection
Renjie Liu, Hechao Chen, Chun Xia
Utilizing multi-wavelength data from the Solar Dynamics Observatory, we report the first imaging detection of reconnection jets driven by the footpoint drift of an erupting hot-cha…
Successive Coronal Jets as Novel Facilitators for Filament Oscillation and Eruption
Chengrui Zhou, Chun Xia, Wentai Fu +2
Solar filament eruptions are central to coronal mass ejections and space weather, yet their triggering mechanisms remain a fundamental open question. In particular, the early-stage…
The Spontaneous Genesis of Solar Prominence Structures Driven by Supergranulation in Three-Dimensional Simulations
Huanxin Chen, Chun Xia, Hechao Chen
Solar prominences usually have a horizontally elongated body with many feet extending to the solar surface, resembling a multi-arch bridge with many bridge piers. The basic mechani…
Observational Analysis of Multi-thermal Counter-streaming Flows in a Forming Filament and Their Relationship with Local Heating at Filament Footpoints
Hongrui Li, Hechao Chen, Chun Xia +3
Utilizing high-resolution imaging and spectroscopic observations from the New Vacuum Solar Telescope (NVST), the Interface Region Imaging Spectrograph (IRIS), and the Solar Dynamic…
Formation of Polar Crown Filaments Magnetic Fields by Supergranular Helicity Injection
Huanxin Chen, Chun Xia, Hechao Chen
To understand the magnetic fields of the polar crown filaments (PCFs) at high latitudes near polar regions of the Sun, we perform magnetofrictional numerical simulations on the lon…
