Variations of the vector magnetic structures in the solar polar regions observed by Hinode
Shuhong Yang, Chunlan Jin, Qiao Song +7
Using the polar vector magnetic field data observed by Hinode from 2012 to 2021, we study the long-term variations of the magnetic flux, the flux proportion of different polarities…

Observational study of the formation of homologous confined circular-ribbon flares
Shuhong Yang, Ruisheng Zheng, Yijun Hou +5
When several solar flares with comparable classes occur successively at the same location and exhibit similar morphological features, they are called homologous flares. During 2012…
