MMMRN test at t_core + 1 kyr and t_core + 2 kyr (t_core =72.84 kyr). Edge-on and mid-plane cuts of the gas and the dust densities for the least coupled species are provided (left and rights respectively). Values of the gas density are indicated by the colorbar at the bottom. Dust densities have been multiplied by a factor 100 to be represented on the same scale. Hence, colors of the gas and the dust maps match when the dust-to-gas ratio equals its initial value 0.01. Dust densityvariations in regions where ɛ₀ρ_d < min(ρ_g) have voluntarily not been displayed to highlight the enriched regions. These depleted regions are delimited by the dashed gray lines. This choice of colors applies for all density maps in this study. Gas and dust are clearly not perfectly coupled.
