Abstract | Theory suggests that the orbits of a large fraction of binary systems, including planet-star binary systems, shrink by a few orders of magnitude after formation. But so far, only one hot Jupiter with tidally driven orbital decay has been found by transit timing variations. We propose to search for orbital decay companions in heartbeat star systems because the orbital angular momentum is effectively transferred to the host star, causing tidal dissipation. KIC 3766353 is one of the heartbeat stars with tidally excited oscillations. We acquired the primary and the secondary eclipse time variations from the Kepler photometric light curves. Timing analysis shows that KIC 3766353 is a hierarchical triple system with a hidden third body and a red dwarf (mass 0.35 M-circle dot, radius 0.34 R-circle dot) in its inner orbit. The minimum mass of the third body is similar to 0.26 M-circle dot, and the distance from the inner orbital is similar to 111.4 R-circle dot. The period decay rate of the red dwarf is approximately 358 ms yr(-1). The combined effects of the light-traveltime and the orbital decay lead to the observed timing variations. Future monitoring with long-time baseline observations is required to delve into the contributions of these two effects. |
