Simulation results in the form of polar plane cross-sections for the perpendicular (left column), intermediate (middle column), and quasiparallel (right column) simulation run. The first row a−c) shows the magnetic field, the second row d−f) the ionospheric density, and the third row g−i) the stellar wind density. The x and z axes are in units of R_p. A selection of ion trajectories (red) originating in the higher south pole ionosphere and projected on to the polar plane have been added to d−f). The trajectories in f) are identical to those in Fig. 8a.
