Post-Main Sequence Debris Disks

Although debris discs around main sequence stars are relatively well understood, very little is known about what happens to these systems as the star evolves. There are a growing number of observations of dust around evolved stars, including white dwarfs with dusty discs within the tidal radius of the star, as well as a handful of systems with at 10-100AU, similar to on the main sequence. In our group we have been considering the evolution of planetary systems (including their debris discs) beyond the main sequence, with a particular focus on explaining the observations.
