Result for a disk viscosity of α = 10⁻³ (model setup VII). The mass estimates in this simulation are 8 M_Jup for the inner and 3 M_Jup for the outer planet. Because this setup shows the best agreement with the modeled ALMA image of all our results, we further simulated an observation with ALMA based on the unconvolved RADMC-3D output to prove the observability of the simulated substructures. This simulated observation is shown in panel c of this figure.
