Magnetic helicity evolution during active region emergence and subsequent flare productivity
Zheng Sun, Ting Li, Quan Wang +3
Aims. Solar active regions (ARs), which are formed by flux emergence, serve as the primary sources of solar eruptions. However, the specific physical mechanism that governs the eme…
