Upper panel: MEGNO map of KIC 4862625b. The masses of primary and secondary component were set to 1.47  M _☉ and 0.37  M _☉, respectively. The binary semi-major axis and eccentricity were set to 0.177 AU and 0.2. The planet was treated as a test particle. The cross-hair marks the best-fit osculating elements ( a, e) = (0.64 AU, 0.1) of the planet. Arrows indicate the location of mean-motion resonances. Yellow (or light) color denotes chaotic (possibly unstable) orbits and blue (dark) color denotes quasi-periodic orbits with | Y − 2.0| 0.001. Lower panel: same as the upper panel but now zooming into a narrower region of ( a, e)-space of the planet.
