Abstract:
---------
The interaction of magnetic fields and stratified convection was
studied in the context of the solar and late type stellar dynamos by
using numerical 3D MHD simulations. The topology
of stratified asymmetric and over-turning convection enables a pumping
mechanism that may render the magnetic flux storage problem obsolete.
The inclusion of open boundary conditions
leads to a considerable flux
loss unless the open boundary is placed close to the physical boundary.
Simulations including solar-like latitudinal shear indicates that a toroidal
field of several tens of kilo-Gauss may be held down by the pumping
mechanism.
