A photometric method to detect planets orbiting around shortperiodic binary stars is presented. It is based on the detection of eclipse-signatures in the reﬂected light of circumbinary planets. Amplitudes of such ’reﬂected eclipses’ will depend on the orbital conﬁgurations of binary and planet relative to the observer. Reﬂected eclipses will occur with a period that is distinct from the binary eclipses, and their timing will also be modiﬁed by variations in the light-travel time of the eclipse signal. For the sample of eclipsing binaries found by the Kepler mission, reﬂected eclipses from close circumbinary planets may be detectable around at least several dozen binaries. A thorough detection eﬀort of such reﬂected eclipses may then detect the inner planets present, or give solid limits to their abundance.
