Unstable low-mass planetary systems as drivers of white dwarf pollution
A new study examining white dwarf pollution, and featuring contributions from CEH members Dimitri Veras and Boris Gänsicke, concludes that if planet-planet scattering is responsible for the phenomenon then many such objects can be expected to host (currently undetectable) super-Earth planets on orbits of several au and beyond.
