The bulk density of dust aggregates is an important factor in collisional growth of dust in
protoplanetary disks. The density of aggregates changes the coupling with the disk gas,
which governs the motion of aggregates in disks. Collisional outcomes also depend on the
aggregate density. We perform three-dimensional N-body simulations of sequential
collisions of aggregates composed of a number of submicron-sized icy particles in order to
investigate the density evolution of dust aggregates growing in protoplanetary disks. In the …
