Query: On the transport of magnetic fields by solar-like stratified convection   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.
