Results for the simulations with a single planet, positioned at 13 au with a mass of 8 M_Jup (position marked in panel d as a dashed vertical line). The two simulation results correspond to different initial density models. Simulation I started with a power law (Eq. (8)) for the radial fall-off of Σ_g∕d and simulation II with a self-similar solution profile (Eq. (9)). We present them as synthetic observations convolved with a 0.3″ beam (panels b and c) in direct comparison to the modeled ALMA image (panel a).
