Scientific paper

We study the stability and possible detection of an Earth-like planet in a 3-Body transiting "Hot Jupiter" system. Orbital stability is quantified by calculating MEGNO for a wide range of (a,e) parameter space. We pay special attention to detect the location of mean-motion resonances. To confirm orbital stability we apply long-term numerical orbit integrations. For special high-eccentric orbits of the Earth-mass planet we calculate the transit-timing variation signal and discuss detection of the Earth-like planet as inferred from recurrent transit observations.
