Topolopy of the nonoscillating solution in the meridional plane. In a) zoom out showing the collimation. In b) zoom close to the star. All distances are given in astronomical units (AU). The solid (red) lines correspond to open fieldlines connected to the star. The dashed (green) lines correspond to closed stellar fieldlines and lines connected to the disk. All open lines are originating in a polar cap extending to a colatitude of 15 degrees. The dotted circle indicates the Alfvén surface.
