Abstract: Wide - field searches for transiting extra-solar giant planets face the difficult challenge of separating true transit events from the numerous false positives caused by isolated or blended eclipsing binary systems.
Not exact matches
But other observations need to confirm the true planetary nature of these candidate events, because the observed dips may also be due to an eclipsing binary star in the background whose light blends with the foreground star studied by Kepler.
Detailed simulations of blend models composed of an eclipsing binary plus a third star diluting the eclipses were compared with the observed light curve and used to derive the properties of the three components.
When combined they yield a transit depth of 344 \ pm 85 ppm that is consistent with the depth in the Kepler passband (376 \ pm 9 ppm, ignoring limb darkening), which rules out blends with an eclipsing binary of a significantly different color than the target.
A blend may consist of a background or foreground eclipsing binary (or star - planet pair) whose eclipses are attenuated by the light of the candidate and possibly other stars within the photometric aperture.
For an additional candidate, we present multi-color follow - up photometry during a subsequent time of eclipse, which reveals that this candidate consists of a blend of an eclipsing binary and a physically unassociated star.
