Description

With this contribution we pointed out that a binarogram is also useful to detect a small orbit or short orbital period (below 50 d) Kepler binaries. This is possible by through extracting orbital frequencies of each binarogram in the combination to investigate the nature of the peak. Then by constructing the Peak-Indicator (PI) or the horizontal and vertical line which is a key to show the behaviour of the peak in detail. Previously, peoples have been limiting them selves to apply this method on pulsators which have less than 50 d orbital period. Now we have discussed that the method is applicable even in case the orbital period of a pulsator is less than 20 d. We put a side a detail discussion of how this Modified Binarogram can be constructed for the next contribution and we pointed out  we expanded the method as suggested in this poster.
