OSSOS: constraints on resonant trans-Neptunian populations from the full survey sample
Résumé
The Outer Solar System Origins Survey (OSSOS) has discovered more than 300 objects in mean motion resonances with Neptune, including more than 100 objects in Neptune’s 3:2 resonance. This quadruples the available characterized sample of resonant trans-Neptunian objects. This sample can be used to test models of the current populations of these resonances and the distributions of objects within them, which will provide valuable constraints on the dynamical history of Neptune. We will report on the distribution of objects within the 3:2 resonant population and provide updated constraints on their H magnitude and eccentricity distribution. We will provide an updated estimate of the intrinsic population ratios between Neptune’s resonances based on the full OSSOS sample, highlight interesting constraints for individual resonant populations, and report new discoveries in resonances not previously known to be occupied.
