The role of cluster evolution in disrupting outer planetary systems via the Kozai mechanism

Several studies have shown that a high proportion of exoplanets orbit a component of a binary system. It is thought that the Kozai mechanism may play a significant role in disrupting the orbits of planets in binary systems, and it has been shown that it can cause high eccentricities in planetary orbits. I show that the Kozai mechanism can be induced in planets orbiting binary components by the dynamical processing of the initial population in a typical star cluster. In particular, I discuss the implications of the Kozai mechanism for outer planetary systems.
