Extrasolar Planet Interactions

  title={Extrasolar Planet Interactions},
  author={Rory K. Barnes and Richard Greenberg},
The dynamical interactions of planetary systems may be a clue to their formation histories. Therefore, the distribution of these interactions provides important constraints on models of planet formation. We focus on each system’s apsidal motion and proximity to dynamical instability. Although only ∼25 multiple planet systems have been discovered to date, our analyses in these terms have revealed several important features of planetary interactions. 1) Many systems interact such that they are… CONTINUE READING
