Migration map based on the equilibrium state of the protoplanetary disk. The colour code shows the normalised value of the total torque γΓ_tot/ Γ₀ acting on an embryo with the mass M_em (vertical axis) placed on a circular orbit at the radial distance r (horizontal axis) in the disk. Calculated according to Paardekooper et al. (2011), using the constant kinematic viscosity ν = 5 × 10¹⁴ cm² s^-1 and the potential smoothing parameter ϵ = 0.4H_em.
