Fig. 1
Semi-major axis as a function of time for an example of a three-planet EMS system (see the text for the full initial conditions). The envelope of the curve represents the extent of the orbits. We note the discontinuous vertical axis. We show the time where the first main two-planet MMR is crossed. The system becomes unstable soon afterwards.
