TLDR
In this paper, the two-body problem and the restricted three body problem are considered. And the disturbing function is extended to include the spin-orbit coupling and the resonance perturbations.Abstract:

Orbital resonances in the inner neptunian system. II. Resonant history of Proteus, Larissa, Galatea, and Despina
Ke Zhang,Douglas P. Hamilton +1 more
TL;DR: Zhang et al. as discussed by the authors investigated the orbital history of the small neptunian satellites discovered by Voyager 2 and found that the current orbital inclinations of Proteus, Galatea, and Despina are consistent with resonant excitation if they have a common density 0.4 < ¯ ρ < 0.8g /cm 3.

Condition for capture into first-order mean motion resonances and application to constraints on the origin of resonant systems
TL;DR: In this article, the authors derived the critical migration timescale for capture into the 2:1 resonance with a wide range of various parameters, including the planet-to-stellar mass ratio, and its dependence exhibits power-law behavior.

Slow Modes in Keplerian Disks
TL;DR: In this article, the authors investigate the properties of slow modes, using softened self-gravity as a simple model for collective effects in the disk, and find that all slow modes are stable.

Are the kepler near-resonance planet pairs due to tidal dissipation?
TL;DR: In this paper, the authors consider a scenario in which pairs of planets were captured into first-order resonances by migration due to planet-disk interactions, and subsequently became detached from the resonances, due to tidal dissipation in the planets.

Binaries in the Kuiper Belt
TL;DR: Binaries have played a crucial role many times in the history of modern astronomy and are doing so again in the rapidly evolving exploration of the Kuiper Belt as mentioned in this paper, which has been an unanticipated windfall.
