Description

The incoming Roman Galactic Exoplanet Survey promises to detect more than 1500 bound planets by the microlensing technique. These planets are particularly precious as they cover a corner of the parameter space barely touched by other methods (1-10 au orbits down to Mars mass planets). In addition, hundreds of free-floating planet detections will shed light on these mysterious wanderers. The Italian contribution consists in the development of the most efficient tools for fast and robust interpretation of microlensing events, including advanced computational algorithms that are now a standard in the community. In preparation of the Roman survey, we have already performed a precursor survey with the Euclid space telescope. Thousands of past microlensing events can be reviewed with these new data upgrading the scientific information of twenty years of surveys.
