Torque evolution in disks described in Fig. 12. Top panel: disks with T-dependent opacities. Bottom panel: disks with r-dependent opacities. The individual cases are distinguished by colour and labelled in the legend. The evolution from the κ_BL -disk simulation (solid grey curve) is given for reference. In the top panel, the torque amplitude diminishes with the power-law index of theopacity law, yet the oscillations appear in all studied cases. In the bottom panel, we find that oscillations are rapidly damped.
