CEH member David Armstrong has published a new study on automatic vetting of exoplanet candidates using machine learning techniques. In this work he applies it to candidates from NGTS, but the technique is extendable to other transiting exoplanet surveys.

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.

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.
