| Abstract: |
The results of a 2D numerical simulation of the rise of twisted magnetic flux tubes are sketched. The theoretical criterion for the minimum twist necessary to prevent the conversion of the tube into a pair of strong vortices is shown to be correct. The transition from a low-twist to a high-twist regime is exemplified. There is a sharp transition between the tube interior and the outside medium. A well-developed wake is formed, which however contains only a fraction of the original magnetic flux of the tube. |
