Figure 3: Evolution of the jet radius (radius of the truncation field line) for models CD1, ER2 and also the unchanged analytical solution ADO, at two representative z values above the equatorial plane (z = 10 and z = 25 in the models ER2 and ADO; z = 10 and z = 50 in the model CD1). The models ADO and ER2 are stationary while the model CD1 collapses. |
