Gas density (logarithmic scale) at the midplane at t = 11 orbits. The zoomed regions correspond to an area similar to that shown in Fig. around the planetary embryo. In these regions, no low-density structures resembling hot lobes were observed. The solid purple lines indicate the corotation radii. The dashed yellow and dotted green lines mark the locations of the magnetic resonances for ß = 50 and ß = 1000, respectively. The white plus symbol denotes the position of the planetary embryo.
