Magnetic Helicity from Multipolar Regions on the Solar Surface
Philippe-A. Bourdin, Axel Brandenburg
The emergence of dipolar magnetic features on the solar surface is an idealization. Most of the magnetic flux emergence occurs in complex multipolar regions. Here, we show that the…

Magnetic Helicity Reversal in the Corona at Small Plasma Beta
Philippe-A. Bourdin, Nishant K. Singh, Axel Brandenburg
Solar and stellar dynamos shed small-scale and large-scale magnetic helicity of opposite signs. However, solar wind observations and simulations have shown that some distance above…
