Exo-planet detection with the COROT space mission. I. A multi-transit detection criterion
In this Note, we present a detection criterion for exo-planets to be used with the space mission COROT. This criterion is based on the transit method, which suggests the observation of star dimming caused by partial occultations by planetary companions. When at least three transits are observed, we show that a cross-correlation technique can yield a detection threshold, thus enabling the evaluation of the number of possible detections assuming a model for the stellar population in the Galaxy.
