A semi-analytical Ring-Arc model for Plutino perturbations
Yue Chen, Jian Li
Neptune's 2:3 mean motion resonance induces an asymmetric spatial distribution of Plutinos. We previously proposed a 9000-point-mass arc model that successfully captures the result…

A new multiple-arc model of the resonant Kuiper belt objects -- Plutinos
Yue Chen, Jian Li
To incorporate the gravitational influence of Kuiper belt objects (KBOs) in planetary ephemerides, uniform-ring models are commonly employed. In this paper, for representing the KB…
