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:

Forced Resonant Migration of Pluto's Outer Satellites by Charon
William R. Ward,Robin M. Canup +1 more
TL;DR: The orbital periods of the two new moons of Pluto are nearly integer multiples of Charon's period, suggesting that they were driven outward by resonant interactions with Charon during its tidal orbital expansion.

An Introduction to Celestial Mechanics
TL;DR: The authors provides a clear and concise treatment of virtually all of the major features of solar system dynamics, such as rigid body rotation, Langrangian mechanics and orbital perturbation theory.

Planetary Magnetic Dynamo Effect on Atmospheric Protection of Early Earth and Mars
Véronique Dehant,Helmut Lammer,Yu. N. Kulikov,Jean-Mathias Grießmeier,Doris Breuer,O. Verhoeven,O. Karatekin,T. Van Hoolst,Oleg Korablev,P. H. Lognonné +9 more
TL;DR: In this paper, the authors examined the impact of the magnetic field on the atmosphere of Mars and found that a much weaker early martian magnetic field, a late onset of the dynamo, and high erosion rates of a denser early atmosphere.

On the Misalignment of the Directly Imaged Planet β Pictoris b with the System's Warped Inner Disk
TL;DR: In this article, the authors explore three scenarios for reconciling the apparent misalignment of the directly imaged planet β Pictoris b with the warped inner disk of β Pictis, and find that, at the extremes of the uncertainties, the orbit of the planet has the inclination necessary to produce the observed warp, and if planet b were aligned with the flat outer disk, it would prevent another planet from creating a warp with the observed properties; therefore planet b itself must be responsible for the warp.

The EVIL-MC Model for Ellipsoidal Variations of Planet-hosting Stars and Applications to the HAT-P-7 System
Brian Jackson,Brian Jackson,Nikole K. Lewis,Jason W. Barnes,L. Drake Deming,Adam P. Showman,Jonathan J. Fortney +6 more
TL;DR: In this article, a new model for ellipsoidal variations induced by a low-mass companion, the EVIL-MC model, was proposed to analyze Kepler Quarter 0-2 (Q0-2) observations of the HAT-P-7 system, an F-type star orbited by a ∼ Jupiter mass companion.
