White dwarf planets in star clusters: gravitational scattering versus mass-loss effects
Richard J. Parker, Dimitri Veras
White dwarfs are unique laboratories for understanding the formation, evolution and survivability of planetary systems. Post-main sequence mass-loss will change planetary orbital p…
Size limits on tidal debris around white dwarfs: the km-size barrier
Jordan K. Steckloff, Dimitri Veras, Kathryn Volk
Compact disks of planetary debris orbiting white dwarfs provide a crucial window into our understanding of evolved planetary systems. The formation of these disks has been widely m…
DebrisWatch II: Digging deeper for geosynchronous debris
James A. Blake, Benjamin F. Cooke, Cristina Paragini +27
The geosynchronous (GSO) debris environment is continually evolving. Regular monitoring of the region is consequently of great importance, though the trade-off between coverage and…
Producing planetary debris exterior to white dwarf Roche radii through sublimative rotational fission
Dimitri Veras, Jordan K. Steckloff, Kathryn Volk
The majority of white dwarfs that host periodic transiting planetary debris do so at distances that exceed the rubble-pile Roche limit, in disagreement with canonical formation mod…
The evolution of exocomets and their source populations
Alexander J. Mustill, Tim Pearce, Michele Bannister +12
We review the current state of knowledge of the long-term evolution of the small bodies that give rise to comets and exocomets, as well as their reservoirs. The active cometary pha…
Exocometary physics: material release and tails
Théo Vrignaud, Dennis Bodewits, Jake Hanlon +5
Despite decades of observations, the physical processes governing mass loss from small bodies beyond our Solar System remain poorly constrained. These exocomets are often treated a…
