The animation below shows the time evolution of model C2R90, projected on the equatorial plane. The three sections of the animation represent the time evolution of (1)  the spatial distribution of particles, (2) the spatial distribution of particles with individual trails, and (3) the smoothed surface density, respectively.


The numerical simulations were carried out with the software environment STARLAB on HPC Cluster Cassini at Drexel University, Department of Physics.

The visualizations have been performed in collaboration with David Reagan and William Sherman (Advanced Visualization Lab, Indiana University). The Advanced Visualization Lab at Indiana University is a unit of the Research Technologies division of University Information Technology ServicesResearch Technologies is a Pervasive Technology Institute Cyberinfrastructure and Service Center.
