Astrophysical false positives that mimic planetary transit are one of themain limitation to exoplanet transit surveys. In this proceeding, we review theissue of the false positive in transit survey and the possible complementaryobservations to constrain their presence. We also review the false-positiverate of both Kepler and CoRoT missions and present the basics of theplanet-validation technique. Finally, we discuss the interest of observingbright stars, as PLATO 2.0 and TESS will do, in the context of the falsepositives. According to simulations with the Besan\c{c}on galactic model, wefind that PLATO 2.0 is expected to have less background false positives thanKepler, and thus an even lower false-positive rate.

Astrophysical false positives in exoplanet transit surveys: why do we need bright stars ?
