We simulated passing planetesimals through the circumplanetary disks of Jupiter and Saturn and capture of their material into the disks with consideration of combined processes of aerodynamic braking and ablation of planetesimals in the disk’s gas medium. There is a significant dependence on the ablation coefficients of the amount of material captured by the disk. For ablation factors <0.01 s2km-2, the contribution of ablation to the captured mass can be ignored, however, for planetesimals from cometary material, ablation can supply 20-30% of the mass of planetesimals in the feeding area of Ganymede and Callisto and 10%-20% in the feeding area of Titan.
