Descripción
The physics of a twisted magnetic flux tube rising in a stratified
medium is studied using a numerical MHD code. The problem considered is
fully compressible (no Boussinesq approximation), includes ohmic
resistivity, and is two dimensional, i.e., there is no variation of the
variables in the direction of the tube axis. We study a high plasma beta
case with small ratio of radius to external pressure scaleheight. The
results obtained can therefore be of relevance to understand the
transport of magnetic flux across the solar convection zone.
