Evolution of the normalized total mass of solid particles in the disk for different values of ɛ ∈ {0.001, 0.01, 0.1, 0.5} and disk mass μ = M_disk∕M_⊙∈{0.01, 0.02, 0.05}. Different colors correspond to the different species (red: planetesimals, yellow: dust, blue: pebbles, black dotted lines: dust and pebbles combined), the solid lines to primordial and the dashed lines to collisional populations. Left panels: disk mass increases from top to bottom while the trap efficiency ɛ remains constant. Likewise, in the right panels: trap efficiency increases downward, however the middle left panel would also fit within this sequence between the top right and the middle right panel.
