The critical role of magnetic helicity in astrophysical large-scale dynamos
Axel Brandenburg
The role of magnetic helicity in astrophysical large-scale dynamos is reviewed and compared with cases where there is no energy supply and an initial magnetic field can only decay.…
Small-scale magnetic helicity losses from a mean-field dynamo
Axel Brandenburg, Simon Candelaresi, Piyali Chatterjee
Using mean-field models with a dynamical quenching formalism we show that in finite domains magnetic helicity fluxes associated with small-scale magnetic fields are able to allevia…
The role of the Yoshizawa effect in the Archontis dynamo
Sharanya Sur, Axel Brandenburg
The generation of mean magnetic fields is studied for a simple non-helical flow where a net cross helicity of either sign can emerge. This flow, which is also known as the Archonti…
Advances in theory and simulations of large-scale dynamos
Axel Brandenburg
Recent analytical and computational advances in the theory of large-scale dynamos are reviewed. The importance of the magnetic helicity constraint is apparent even without invoking…
Paradigm shifts in solar dynamo modeling
Axel Brandenburg
Selected topics in solar dynamo theory are being highlighted. The possible relevance of the near-surface shear layer is discussed. The role of turbulent downward pumping is mention…
Turbulent diffusion with rotation or magnetic fields
Axel Brandenburg, Andreas Svedin, Geoffrey M. Vasil
The turbulent diffusion tensor describing the evolution of the mean concentration of a passive scalar is investigated for non-helically forced turbulence in the presence of rotatio…
