The Link Between Planetary Systems, Dusty White Dwarfs, and Metal-Polluted White Dwarfs

The Link Between Planetary Systems, Dusty White Dwarfs, and Metal-Polluted White Dwarfs

Authors: John Debes, Kevin Walshe, and Christopher Stark

Purpose: To describe a model by which planetesimals around a white dwarf can be perturbed by the host star's evolution off the main sequence and form dusty debris disks around the white dwarf.
