Evolution of mp(t) and R(t) for dust coagulation as obtained from the semi-analytical model (Eqs. (35) and (36)), for an MMSN disk and α = 10-3. Lines indicate different starting conditions R(t = 0), and are evolved for 106 yrs. Left: compact growth: φ = 1 at all times, and vfrag = 10 m s-1. Right: porous growth: the internal structure of the aggregates is set by hit and stick growth, followed by collisional compaction or gas and self-gravity compaction. Gray lines have no erosion, while black lines show the results for veros = 40 m s-1. Colored lines and -symbols indicate the evolution and steady state peak mass obtained through local MC simulations (Sect. 4.2).
