Title:

Dynamics of Dust in Debris Disks

Abstract:

 Debris disks, like those around Vega, Beta Pictoris, and so on, seem
 to be planetary systems undergoing the last stages of terrestrial
 planet formation.  Images of these dusty circumstellar disks show
 structures that may indicate planets buried within them.  I'll show
 some of the latest supercomputer simulations of planets interacting
 with debris disks and describe how these simulations can be used to
 interpret images of disks made with the Keck Interferometer, Gemini,
 JCMT, and TPF.
