Pebble isolation mass (top plot), maximum Stokes number (middle plot), and planetary growth timescale until the pebble isolation mass is reached (bottom plot) as a function of orbital distance, for disks with α = 10⁻³ and u_f = 10 m s⁻¹. Shown are disks with higher dust-to-gas ratios, f_DG = 2% and f_DG = 3% and higher initial surface density Σ_g,0 = 5000 g cm⁻². For reference the nominal run with Σ_g,0 = 2000 g cm⁻² and f_DG = 1.5% is included.
