英文摘要
I carried out numerical simulations of collisions between dust aggregates consisting of submicron grains to construct a growth model of dust to planetesimals in protoplanetary disks. In particular, I focus on the effects of bouncing process, the mass ratio of colliding aggregates, and the monomer size distributions in aggregates. As a result, I found that icy dust aggregates are able to grow in protoplanetary disks, but silicate dust aggregates are still difficult to grow. We need study more in wider ranges of parameters and the effects of other factors.
