The dual role of shear in large-scale dynamos
Axel Brandenburg
The role of shear in alleviating catastrophic quenching by shedding small-scale magnetic helicity through fluxes along contours of constant shear is discussed. The level of quenchi…
A growing dynamo from a saturated Roberts flow dynamo
Andreas Tilgner, Axel Brandenburg
Using direct simulations, weakly nonlinear theory and nonlinear mean-field theory, it is shown that the quenched velocity field of a saturated nonlinear dynamo can itself act as a…
Nonlinear magnetic diffusivity and alpha tensors in helical turbulence
A. Brandenburg, K. -H. Rädler, M. Rheinhardt +1
The effect of a dynamo-generated mean magnetic field of Beltrami type on the mean electromotive force is studied. In the absence of the mean magnetic field the turbulence is assume…
Modeling a Maunder Minimum
A. Brandenburg, E. A. Spiegel
We introduce on/off intermittency into a mean field dynamo model by imposing stochastic fluctuations in either the alpha effect or through the inclusion of a fluctuating electromot…
Kinematic alpha effect in isotropic turbulence simulations
Sharanya Sur, Axel Brandenburg, Kandaswamy Subramanian
Using numerical simulations at moderate magnetic Reynolds numbers up to 220 it is shown that in the kinematic regime, isotropic helical turbulence leads to an alpha effect and a tu…
The solar interior - radial structure, rotation, solar activity cycle
Axel Brandenburg
Some basic properties of the solar convection zone are considered and the use of helioseismology as an observational tool to determine its depth and internal angular velocity is di…
