For instance, the most prolific method for detecting exoplanets and inferring several of their characteristics, transit photometry, is very sensitive to the presence of stellar spots.

We train a probabilistic Long Short-Term Memory (LSTM) network to predict the next data point of the light curve during the out-of-transit, and use this model to reconstruct a transit-free light curve - i. e. including only the systematics - during the in-transit.

Further advances in exoplanet detection and characterisation require sampling a diverse population of extrasolar planets.
