One specific type of such candidates are Duotransits - candidates with two transits separated by a large gap (as is the case for around 400 TESS candidates observing in the primary and extended missions). Here Cheops is perfectly placed to recover the periods of such long period planets by observing potential period aliases. In this program we propose to use this method to recover the periods of super-Earths and Neptunes around bright stars with Cheops. [truncated! Please see actual data for full text]
