We examine the effects that dynamical instability has on shaping the orbital properties of exoplanetary systems. Using N-body simulations of non-EMS (Equal Mutual Separation), multiplanet systems we find that the lower limit of the instability time-scale t is determined by the minimal mutual separation Kmin in units of the mutual Hill radius. Planetary systems showing instability generally include planet pairs with period ratio... (See abstract in article).
