Observations of Magnetic Helicity Proxies in Solar Photosphere: Helicity with Solar Cycles
Hongqi Zhang, Shangbin Yang, Haiqing Xu +3
Observations of magnetic helicity transportation through the solar photosphere reflect the interaction of turbulent plasma movements and magnetic fields in the solar dynamo process…

Current helicity constraints in solar dynamo models
D. Sokoloff, H. Zhang, D. Moss +5
We investigate to what extent the current helicity distribution observed in solar active regions is compatible with solar dynamo models. We use an advanced 2D mean-field dynamo mod…
