Statistical Study of Solar Prominence Plumes Based on NVST H Observations
Yangrui Chen, Yijun Hou, Jincheng Wang +9
Plumes are one of the most representative dynamic features observed in prominences and play a key role in mass and magnetic transport within them. However, their physical nature an…
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…
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)…
Can We Distinguish the Source Region Location of Filament/Prominence Eruptions from the Sun-as-a-star H Spectrum?
Junyi Zhang, Yijun Hou, Xiaofeng Liu +7
Solar filament/prominence eruptions can significantly perturb geospace when originating from favorable source locations and directions. While stellar analogs have been recently rep…
Optical Continuum Light Curves and Bolometric Energy Estimates of Solar White-light Flares
Yingjie Cai, Yijun Hou, Hengkai Ding +2
Solar white-light flares (WLFs) are solar flares exhibiting enhanced emission in the optical continuum. They are critical for understanding energy release and transport mechanisms…
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…
