Randomness and retention: using weak mean motion resonances to constrain neptune’s late-stage migration

HIGHLIGHTS

• What: This model has been used to constrain the Solar System`s planetesimal disc and early planetary migration using the observed population of trans-Neptunian objects (TNOs) in 3:2 first-order mean motion resonance (MMR) with Neptune Murray-Clay and amp; Chiang (hereafter MC2006). This graininess produces a random walk component in semimajor axis for Neptune, similar to the model discussed in this paper. The authors investigate the conditions under which weak resonances can retain TNOs. The authors evaluate how various planetesimal size distributions affect migration to constrain the amount of mass in large objects and . . .
