Final radius versus final semimajor axis of planetesimals in the circum-planetary disk (i.e., at the time of circularization of the orbit according to our criteria, ã ≤ 0.05 R_H ~ 40 R_Jup and ẽ ≤ 0.1). Each planetesimal started with an initial radius R_pl = 100 km at the beginning of the simulation. On the right, the fraction of objects with a size R_pl > R₀, defined as f_> = N(R_pl > R₀)∕N_tot, is reported for different threshold sizes R₀ as indicated by the horizontal blue lines. The histogram at the top shows the corresponding distribution of the final semimajor axis of the planetesimals. The vast majority of planetesimals are captured at distances ≲ 10 R_Jup and are strongly, if not completely, ablated.
