Same as Fig. 4 but we have added here in the fourth row the time evolution of the distance (d_HS)between the host (G70) and the satellite galaxy. This shows clearly the different passages at the pericentric distance and the time of the final plunge (T_Universe∼10.6 Gyr). Here again, we choose the z-axis of the cylindrical coordinate as the total AM vector direction of the stellar component estimated within one effective radius.
