Abstract: | The discovered exoplanetary systems have highly diverse dynamic properties, which differ from those of the Solar System. A
single model including planet migration effects and their gravitational interaction is used to investigate the features of
dynamic processes that lead to the formation of giant-planet systems with different orbital characteristics. It is shown for
a system of four giant planets similar to the Solar System how Type I migration could lead to all the planets being captured
into resonant configurations. The resonant motion can continue for a long period of time after the transition to Type II migration
and after the dissipation of the gas-and-dust disk. The three-planet system of GJ 876 is used to investigate the migration
of the planets inward the orbit of the most massive planet and their capture into low-order resonant configurations under
the conditions of Type II migration. A system similar to the exoplanetary system of HD 102272 is used to study the capture
into high-order resonances followed by an increase in the orbit’s eccentricity. |
