From top to bottom: time evolution of planet’s migration rate, orbital distance, and inverse vortensity ratio I_v,lib/I_v,cross for simulations with Q₀ = 8. The results of our 2D (with FARGO3D) and 1D (with the Bern model) simulations are shown side by side for easy direct comparison. Lines are coloured by α_vis and different line styles indicate varying slopes of the surface density, β. The migration rates of the 2D simulations (top left panel) are shown as moving averages over 100 orbits. For the 1D simulations (right), we additionally show results of simulations that discard the dynamical corotation torque as transparent lines. For an easier direct comparison of the most relevant simulations, see the left column in Figure B.1 of Appendix B.
