Revisiting Approaches to Stellar White-Light Flare Energy Based on Spatiotemporally Resolved Solar Observations
Yingjie Cai, Yijun Hou, Ting Li +5
Accurately estimating the bolometric energy of solar and stellar white-light flares (WLFs) is crucial for understanding their physical nature and impact on surrounding planets. How…
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…
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…
The Mini-SiTian Array: first-two-year operation
Min He, Hong Wu, Liang Ge +70
The SiTian project, designed to utilize 60 telescopes distributed across multiple sites in China, is a next-generation time-domain survey initiative. As a pathfinder for the SiTian…
