摘要

We have investigated the evolution of a pair of interacting planets embedded in a gaseous disc considering a possibility of the res-onant capture of a Super-Earth by an inward-migrating Jupiter mass gas giant. It has been found that the terrestrial planet is scattered from the disc or the gas giant captures the Super-Earth into an interior 3:2 or 4:3 mean motion resonance and the stability of such configuration depends on the initial planet positions and eccentricity evolution. The behaviour of the resulting resonant system has been studied numeri-cally by means of the full 2D hydrodynamical simulations. The results are particularly interesting in light of the recent exoplanet discoveries and provide predictions of what will become observationally testable in the near future.
