Binary asteroid formation movies

<p>Simulations of binary asteroid formation using a polyhedral DEM N-body code.&nbsp;</p> <p>Each movie has been rendered in the inertial frame of the system and their titles correspond to the simulation identifier used in the printed article.</p> <p>Due to a bug in the code, some particle phase through the boundary of the primary body which can cause them to be ejected at high velocities as they get too close to the barycentre of the system. Comparing our results with a fixed version of the code where contacts between the primary body and disk particles are resolved, this does not change the dynamics of the disk evolution and the amount of ejected mass remains about the same for each simulation.</p>
