Modelling Dusty Debris Disks
Infrared and sub-millimetre observations of dusty debris disks around young Main Sequence stars often show asymmetries which could be due to the perturbing force of an unseen planet. We are using a modified version of the SWIFT integration package with includes Poynting-Robertson and solar wind drag to model debris disks. This enables us to follow the evolution of a swarm of dust particles in the presence of an unseen extrasolar planet.
