Sheared helical turbulence and the helicity constraint in large-scale dynamos
A. Bigazzi, A. Brandenburg, K. Subramanian
The effect of shear on the growth of large scale magnetic fields in helical turbulence is investigated. The resulting large-scale magnetic field is also helical and continues to ev…
The inverse cascade in turbulent dynamos
Axel Brandenburg
The emergence of a large scale magnetic field from randomly forced isotropic strongly helical flows is discussed in terms of the inverse cascade of magnetic helicity and the alpha-…
Two-dimensional disk dynamos with vertical outflows into a halo
B. von Rekowski, W. Dobler, A. Shukurov +1
We study the effects of vertical outflows on mean-field dynamos in disks. These outflows could be due to thermal winds or magnetic buoyancy. We analyse numerical solutions of the n…
The solar dynamo: old, recent, and new problems
Axel Brandenburg
A number of problems of solar and stellar dynamo theory are briefly reviewed and the current status of possible solutions is discussed. Results of direct numerical simulations are…
Numerical simulations of turbulent dynamos
Axel Brandenburg
Using a periodic box calculation it is shown that, owing to helicity conservation, a large scale field can only develop on a resistive timescale. This behaviour can be reproduced b…
Large scale dynamos with ambipolar diffusion nonlinearity
Axel Brandenburg, Kandaswamy Subramanian
It is shown that ambipolar diffusion as a toy nonlinearity leads to very similar behaviour of large scale turbulent dynamos as full MHD. This is demonstrated using both direct simu…
