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…

MeV-peaked electrons in a coronal source of a solar flare
Gregory D. Fleishman, Ivan Oparin, Gelu M. Nita +3
Analysis of γ-rays in solar flares has suggested a distinct continuum component dominating at MeV energies, which differs from the well-studied X-ray continuum produced by flare-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…
