Comparison of the initial conditions for our protoplanetary disk models: the power-law disk (black), the non-irradiated disk (blue), and the irradiated disk (red). The panels show, from top to bottom, the gas surface density Σ_gas, the temperature T, and the difference between gas and Keplerian rotation, which is equal to the maximum drift speed of dust pebbles ηv_K. Each of the disks has a total mass of 0.1 M_⊙.
