On the ‘Scattered’ Inclinations in the Kuiper Belt

Fred Franklin, Paul Soper

(Submitted on 12 Jan 2015)

This paper shows that the inclinations of bodies captured into mean motion resonances in the Kuiper belt have remained very nearly unchanged, being only slightly increased from initial lower values by migration and/or by long-term planetary perturbations. Thus the observed maximum as high as ~ 30 deg of the i’s of bodies in resonance must reflect either a broad initial range at least to that level for capturable bodies or an elevating process possibly exemplified by the sweeping of secular resonances. We have obtained capture probabilities for 2 well-populated resonances, showing reduced but finite values for i’s up to 35 deg. Whatever led to the present distribution must have produced increases in i for some, but not for all, resonant bodies in the belt.
