Global view of the star-disk interacting system. A logarithmic density map is shown in the background. Poloidal speed vectors are represented as blue arrows. The dotted line marks the Alfvén surface, where . Sample field lines are plotted with white solid lines. Thick yellow field lines, labeled as (a), (b), and (c), delimit the different dynamical constituents of the system indicated in the figure. The image has been obtained by averaging in time the simulation outcome over 54 stellar periods.
