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:

Dynamical instabilities in high-obliquity systems
TL;DR: In this article, it was shown that high-inclination circumplanetary orbits that are gravitationally perturbed by the central star can undergo Kozai oscillations, i.e., large-amplitude, coupled variations in the orbital eccentricity and inclination.

Asymmetric heating of the HR 4796A dust ring due to pericenter glow
Margaret M. Moerchen,Margaret M. Moerchen,L. J. Churcher,Charles M. Telesco,Mark C. Wyatt,R. S. Fisher,Chris Packham +6 more
TL;DR: In this paper, the authors used pericenter glow models to detect brightness and temperature asymmetries of the HR 4796A dust ring at 18 and 25 μm with the 8-m Gemini telescopes.

Pseudo-Newtonian planar circular restricted 3-body problem
TL;DR: In this paper, the authors study the dynamics of the planar restricted three-body problem in the context of a pseudo-Newtonian approximation, and show that most of the pseudo-newtonian configurations are less stable than their Newtonian equivalent.
Journal ArticleDOI
Planetary Trojans: the main source of short period comets?
TL;DR: In this article, the authors present a short review of the impact regime experienced by the terrestrial planets within our own Solar system, describing the three populations of potentially hazardous objects which move on orbits that take them through the inner Solar system.

Physical collisions of moonlets and clumps with the Saturn's F-ring core
TL;DR: In this article, the authors investigate the possibility of dissipative physical collisions of kilometer-size clumps with the F-ring core. But, they only show that it is a viable and efficient mechanism for producing spirals and jets, provided that massive moonlets are embedded in the ring core and that they are impacted by loose clumps orbiting in the Fring region.
