Modelling and removal of transients and systematics for exoplanet discovery
In recent years there has been a revolution in the detection of extra-solar planets, driven by missions such as the Kepler Space Telescope. There are now over 2000 known
extrasolar planets, and discovery work continues apace on many fronts. The problems associated with systematic artefacts in the data, from instrumentation and from the intrinsic variability of host stars, are significant. In this talk I introduce and discuss the use of flexible Bayesian models to extract systematics, model stellar activity and help clean the data ready for planet detection.
