[39.22] The Effects of Planet-Size Resonant KBOs

M.S. Tiscareno, R. Malhotra (U of Arizona)

Pluto has played an important role in shaping the orbital distribution of KBOs in the 2:3 resonance with Neptune ("Plutinos"). The existence of an object of comparable size in the 1:2 resonance, whether it has since been ejected or simply is yet undiscovered, would have a similarly significant effect on 1:2 resonant KBOs. We will present the results of a series of 1-Gyr integrations of these sections of phase space, including the changes in dynamical diffusion rates caused by planet-size objects at various locations within the resonance.
