[11.01] Long-Term Dynamics and the Classical Kuiper Belt Inclination Distribution

M. J. Kuchner, M. J. Holman (Harvard/Smithsonian Center for Astrophysics)

The inclination distribution of Kuiper Belt Objects is curiously tall compared to planetary and asteroidal inclination distributions. We numerically integrated the orbits of ~1500 particles in the region of the classical Kuiper Belt (41 AU \leq a \leq 47 AU) for 4 billion years to explore the role of dynamical instability in sculpting the inclination distribution in that region. We describe some instabilities that act to increase the mean inclination.
