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…
Sun-as-a-star Analysis of the Solar Eruption Source Region Using Ha Spectroscopic Observations of CHASE
Xiaofeng Liu, Yijun Hou, Ying Li +6
Sun-as-a-star analyses serve as a bridge for comparative studies on solar and stellar activities. To investigate the typical Sun-as-a-star Ha temporal spectral characteristics in s…
Formation of a long filament through the connection of two filament segments observed by CHASE
H. T. Li, X. Cheng, Y. W. Ni +5
We present imaging and spectroscopic diagnostics of a long filament during its formation with the observations from the Chinese H Solar Explorer and Solar Dynamics Observatory.…
