Resonances and chaos in the dynamics of trans-Neptunian objects

November 8, 2019
From 10:30 until 12:00

Melaine Saillenfest



Trans-Neptunian objects have complex orbital dynamics involving mechanisms as diverse as close encounters with Neptune, chaotic scattering driven by resonance overlap, secular effects from the giant planets, isolated mean-motion resonances with Neptune, quasi-integrable cycles from the galactic tides, and random impulses due to passing stars. I will review these mechanisms and present analytical tools providing a qualitative understanding of their effects. I will conclude on how all mechanisms participate to the sculpting of the whole distribution of trans-Neptunian objects.
