PIM (in Earth masses) with effects of dust turbulent diffusion. A comparison between the results of our semi-analytical calculation (solid curves) and those of (Bitsch et al. 2018; dashed curves) for Σ ∝ r^−0.5, uniform aspect ratios and two values of the turbulent viscosity of the disk: α = 10⁻² (upper panel) and α = 5 × 10⁻⁴ (lower panel). The red stars indicate the PIM obtained from our 2D gas plus dust simulations (for h = 0.04).
