The helicity constraint in spherical shell dynamos
A. Brandenburg, P. J. Käpylä, D. Mitra +2
The motivation for considering distributed large scale dynamos in the solar context is reviewed in connection with the magnetic helicity constraint. Preliminary accounts of 3-dimen…
Dynamos in accretion discs
A. Brandenburg, B. von Rekowski
It is argued that accretion discs in young stellar objects may have hot coronae that are heated by magnetic reconnection. This is a consequence of the magneto-rotational instabilit…
Astrophysical significance of the anisotropic kinetic alpha effect
A. Brandenburg, B. v. Rekowski
The generation of large scale flows by the anisotropic kinetic alpha (AKA) effect is investigated in simulations with a suitable time-dependent space- and time-periodic anisotropic…
The effects of vertical outflows on disk dynamos
A. Bardou, B. v. Rekowski, W. Dobler +2
We consider the effect of vertical outflows on the mean-field dynamo in a thin disk. These outflows could be due to winds or magnetic buoyancy. We analyse both two-dimensional fini…
The influence of geometry and topology on axisymmetric mean-field dynamos
E. Covas, R. Tavakol, A. Tworkowski +3
We study the changes in the dynamical behaviour of axisymmetric spherical mean-field dynamo models produced by changes in their geometry and topology, by considering a two paramete…
