On the Nature of Candle-Flame-Shaped Solar Flares and Sub-Alfvénic Supra-Arcade Plasma Downflows
Ivan Oparin, Sabastian Fernandes, Bin Chen +4
Certain solar flares exhibit a distinctive candle-flame or cusp-shaped feature above the bright flare arcade visible in extreme ultraviolet (EUV) and X-ray channels sensitive to hi…
Coronal Mass Ejections Deflected by Newly Emerging Flux: A Combined Analytic and Numerical Study
Yuhao Chen, Chengcai Shen, Zhixing Mei +8
Newly emerging flux (NEF) has been widely studied as a trigger of solar filament eruptions, but its influence on the subsequent dynamics remains poorly explored. Because NEF typica…
Supra-arcade downflows in an extensive fan associated with a giant quiescent solar filament eruption
Xiaoyan Xie, Katharine Reeves, Chengcai Shen +6
We investigate the aftermath of a giant quiescent solar filament eruption on December 24, 2023. One feature of the eruption is an extensive fan above the filament channel that is a…
Energy Conversion and Electron Acceleration and Transport in 3D Simulations of Solar Flares
Xiaocan Li, Chengcai Shen, Xiaoyan Xie +6
Recent observations and simulations indicate that solar flares undergo extremely complex three-dimensional (3D) evolution, making 3D particle transport models essential for underst…
Modeling of Ionization and Recombination Processes in Plasma with Arbitrary Non-Maxwellian Electron Distributions
Chengcai Shen, Xiaocan Li, Yuan-Kuen Ko +4
In astronomical environments, the high-temperature emission of plasma mainly depends on ion charge states, which requires accurate analysis of the ionization and recombination proc…
Anisotropic Turbulent Flows Observed in Above the Loop-top Regions During Solar Flares
Xiaoyan Xie, Chengcai Shen, Katharine Reeves +6
Solar flare above-the-loop-top (ALT) regions are vital for understanding solar eruptions and fundamental processes in plasma physics. Recent advances in 3D MHD simulations have rev…
Theoretical Studies on the Evolution of Solar Filaments in Response to New Emerging Flux
Yuhao Chen, Jialiang Hu, Guanchong Cheng +4
New emerging flux (NEF) has long been considered a mechanism for solar eruptions, but detailed process remains an open question. In this work, we explore how NEF drives a coronal m…
Energetic Electrons Accelerated and Trapped in a Magnetic Bottle above a Solar Flare Arcade
Bin Chen, Xiangliang Kong, Sijie Yu +6
Where and how flares efficiently accelerate charged particles remains an unresolved question. Recent studies revealed that a "magnetic bottle" structure, which forms near the botto…
Dynamical modulation of solar flare electron acceleration due to plasmoid-shock interactions in the looptop region
Xiangliang Kong, Fan Guo, Chengcai Shen +3
A fast-mode shock can form in the front of reconnection outflows and has been suggested as a promising site for particle acceleration in solar flares. Recent development of magneti…
