Stability Limits in Resonant Planetary Systems
Rory Barnes, Richard Greenberg
The relationship between the boundaries for Hill and Lagrange stability in orbital element space is modified in the case of resonantly interacting planets. Hill stability requires…
Apsidal Behavior Among Planetary Orbits: Testing the Planet-Planet Scattering Model
Rory Barnes, Richard Greenberg
Planets in extrasolar systems tend to interact such that their orbits lie near a boundary between apsidal libration and circulation, a "separatrix", with one eccentricity periodica…
Behavior of Apsidal Orientations in Planetary Systems
Rory Barnes, Richard Greenberg
A widely considered characteristic of extra-solar planetary systems has been a seeming tendency for major axes of adjacent orbits to librate in stable configurations. Based on a ne…
Stability Limits in Extra-solar Planetary Systems
Rory Barnes, Richard Greenberg
Two types of stability boundaries exist for any planetary system consisting of one star and two planets. Lagrange stability requires that the planets remain bound to the star, cons…
