Unprecedent fast winking of solar flares triggered by bursty magnetic reconnection
Ting Li, Xuchun Duan, Yijun Hou +13
Flare ribbons form as a result of energy deposition associated with particles accelerated in low layers of the solar atmosphere. The fine-scale structures of flare ribbons, also ca…
Polarity Reversal of the Polar Magnetic Fields in Solar Cycle 25
Yin Li, Shuhong Yang, Yuzong Zhang +4
The polar magnetic field polarity reversal is a key signature of solar cycle evolution, and precise determination of its timing is crucial for dynamo theory validation and solar cy…
Magnetic Evolution of Highly-Sheared Region in Active Region 13842 Producing Large X9.0 Flare
Yijun Hou, Ting Li, Shuhong Yang +8
Shearing motion and magnetic flux cancellation around the polarity inversion line (PIL) play significant roles in the build-up of free magnetic energy and magnetic flux rope (MFR)…
QFP Waves Driven by the Tuning-Fork Effect during Magnetic Reconnecion
Jialiang Hu, Xiaozhou Zhao, Guiping Zhou +8
Through three-dimensional MHD simulations, we have uncovered a kind of fast coronal wave originating from both ends of a current sheet (CS) during a solar eruption. These waves are…
Variations of the vector magnetic structures in the solar polar regions observed by Hinode
Shuhong Yang, Chunlan Jin, Qiao Song +7
Using the polar vector magnetic field data observed by Hinode from 2012 to 2021, we study the long-term variations of the magnetic flux, the flux proportion of different polarities…
A Statistical Analysis of Magnetic Parameters in Solar Source Regions of Halo-CMEs with and without SEP events
Xuchun Duan, Ting Li, Yijun Hou +5
Large SEPs can cause adverse space weather hazard to humans technology and such events are especially associated with halo coronal mass ejections (CMEs). But in turn, a significant…
