Abstract
We study the efficiency of forming large bodies, starting from a sea of
equal-sized planetesimals. This is likely one of the earlier steps of planet
formation and relevant for the formation of the asteroid belt, the Kuiper belt
and extra-solar debris disks. Here we consider the case that the seed
planetesimals do not collide frequently enough for dynamical collisional to be
important (the collisionless limit), using a newly constructed conglomeration
code, and by carefully comparing numerical results with analytical scalings. In
the absence of collisional cooling, as large bodies grow by accreting small
bodies, the velocity dispersion of the small bodies (
