FMA analysis of a Jupiter-size single planet dynamics in a binary system with a_B = 25 AU and e_B = 0. The diffusion index c_s is drawn vs. the semimajor axis of the planet. Small values of c_s means low diffusion, while large values connote chaotic orbits. The yellow filled circle is a case with a large diffusion index which becomes unstable after about 60 Myr. The two filled blue squares are stable cases over 2 Gyr. The green dashed lines show the location of mean motion resonances between the planet and the companion star up to order 10. The black dash-dotted line marks the critical semimajor axis computed from the empirical formula of Holman & Wiegert (1999).
