Resonances in planetary systems

Ivan Shevchenko (Pulkovo Observatory of the Russian Academy of Sciences, Saint Petersburg)

par Gabriel LeMarié - 26 février 2015

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. Theoretical methods and criteria for revealing stability or instability of various planetary configurations are described.
