Binary star detection using the time-delay method: application to 34 Kepler objects of interest.

BALONA L.A.

Abstract (from CDS):

A method is presented whereby the orbital parameters of a pulsating star in a binary or multiple system can be determined using the time delay due to the changing distance of the pulsating star. The method differs from previously published methods in that a direct periodogram of the orbital frequency is derived using all possible information to extract the time delay from the stellar pulsations. The method is easy to use provided the pulsation frequencies are known. The method is tested using various simulations and applied to two stars which have been previously analysed in the literature. Application to 34 Kepler objects of interest which are also δ Sct variables resulted in the detection of five stars which are binaries.
