Unmasking the hidden NGTS-3Ab: a hot Jupiter in an unresolved binary system
The Next Generation Transit Survey, which is led by CEH member Peter Wheatley, has publised its third planet discovery. NGTS-3Ab is in an unresolved binary system, and vetting the planet was a challenging task that produced new insights in BIS correlations in exoplanet observations.

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.
