Abstract
Transiting exoplanets (TEPs) observed just ~10 Myrs after formation of their host systems may serve as the Rosetta Stone for planet formation theories. They would give strong constraints on several aspects of planet formation, e.g. time-scales (planet formation would then be possible within 10 Myrs), the radius of the planet could indicate whether planets form by gravitational collapse (being larger when young) or accretion growth (being smaller when young). We present a survey, the main goal of which is to find and then characterise TEPs in very young open clusters.
Highlights
Detection of flat-bottomed eclipses with the depth of a few tens of millimagnitudes in a light curve of a star suggests the presence of a transiting sub-stellar mass object
The depth of a transit together with the stellar radius give some constraints on the radius of the transiting object
In the 2009 campaign, we found that the light curve of a 15-mag star reveals features typical for a planetary transit
