Modeling setup. Left: schematic representation of the large-scale structure of the interstellar magnetic field disturbed by the accretion disk of a young stellar object (YSO) and taking the shape of an hourglass. The structure of the magnetic fields in the figure is an example and not a complete match. The red arrows indicate axisymmetric jets. The blue rectangle shows the area modeled in the experiment. Right: schematic of the experiment indicating the magnetic field structure with a plasma outflow. The shaded areas are unavailable for diagnostics; the white area illustrates the diagnostic window.
