Where and how flares efficiently accelerate charged particles remains an unresolved question. Recent studies revealed that a \"magnetic bottle\" structure, which forms near the bottom of a large-scale reconnection current sheet above the flare …
Extreme-ultraviolet late phase (ELP) refers to the second extreme-ultraviolet (EUV) radiation enhancement observed in certain solar flares, which usually occurs tens of minutes to several hours after the peak of soft X-ray emission. The coronal loop …
