Discrete element simulations of self-gravitating rubble pile collisions: the effects of non-uniform particle size and rotation

We present a new implementation of a soft-sphere discrete element code to simulate the dynamics of self-gravitating granular materials. The code is used to study the outcome of sub-sonic collisions between self-gravitating rubble piles with masses ranging from 6x10^{21} to 6x10^{22} g. These masses...
