Resonances in the Solar and exoplanetary systems I. I. Shevchenko Pulkovo Observatory Abstract Dynamical problems on the orbital resonances, including mean motion resonances (both two-body and three-body ones) and secular resonances, are considered in application to the dynamics of the Solar and exoplanetary systems. The analyzed systems include multiplanetary (those with two or more than two planets) systems and planetary systems of double stars. ... Circumbinary planets at the "edge of chaos". ...
