Stability of the Kepler‐36 two‐planet system
In this paper we study the dynamics of the Kepler-36 exoplanetary system. The two planets are engaged in the mean-motion resonance of 6:7. The dynamical stability of this system has been studied by numerical methods using a Lie-integrator and calculating the Lyapunov characteristic indicator (LCI) and maximum eccentricity (ME). We studied the stability of the system, the stability of another planet, and the stability of satellites belonging to the known planets. The possibility of trojans were also studied using the massless approximation. The tidal perturbations were neglected although they can become significant in some cases.

Abstract It is suggested that a major source of the recently observed large multiplicity fluctuation satisfying KNO scaling in p p collider experiments is the fluctuation of the impact parameter b . Conssequences of the association of the KNO variable z with b are discussed.
