Observational Evidence for Counter-helicity Magnetic Reconnection in a Solar Eruption

Jinrui Chang, Yi Bi, Bo Yang +3

The paper presents multiwavelength observations and magnetic field modeling of an M7.0 solar flare, showing that reconnection between a low‑lying positive‑helicity core field and a…

Machine Learning-based Separation of the He I 10830Ã Chromospheric Signal: Quantitative Analysis of Chromosphere-Corona Intensity in the Quiet Sun

Huaiming Li, Fangyu Xu, Yi Bi +1

The He I 10830Ã line, a crucial optically thin chromospheric line, is frequently used to study coronal heating and vertical coupling across the chromosphere-corona interface. Howev…
