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:

On the Chaotic Orbits of Disk-Star-Planet Systems
Ing-Guey Jiang,Li-Chin Yeh +1 more
TL;DR: In this article, two ways of setting initial velocities are used in numerical surveys to explore possible chaotic and regular orbits for disk-star-planet systems, and the chaotic boundary does not depend much on disk mass for type I initial conditions, but can change a lot for different disk masses for type II initial conditions.

The Curiously Warped Mean Plane of the Kuiper Belt
Kathryn Volk,Renu Malhotra +1 more
TL;DR: In this paper, the authors measured the mean plane of the Kuiper Belt as a function of the semimajor axis and found a statistically significant warp near the 40.3-42-approximation.

Methods for orbit optimization for the lisa gravitational wave observatory
Zhaohua Yi,Zhaohua Yi,Guangyu Li,Gerhard Heinzel,Albrecht Rüdiger,Oliver Jennrich,Li Wang,Yan Xia,Fei Zeng,Haibin Zhao +9 more
TL;DR: In this paper, several problems of the orbit optimization of the LISA constellation are discussed by using numerical and analytical methods for satisfying the requirements of accuracy, and the principle for selecting the optimum starting elements of orbits at any epoch is proposed.

Two super-earths orbiting the solar analog HD 41248 on the edge of a 7 : 5 mean motion resonance
James S. Jenkins,James S. Jenkins,Mikko Tuomi,Mikko Tuomi,Ramon Brasser,O. Ivanyuk,Felipe Murgas +6 more
TL;DR: In this article, the discovery of two super-Earths that are close to a second-order dynamical resonance orbiting the metal-poor G2V star HD?41428 was reported.
Journal ArticleDOI
Stability of the 47 UMa planetary system
TL;DR: In this article, the stability of the 47 UMa planetary system in the framework of the N-body problem was studied with application of the MEGNO technique, which makes it possible to distinguish rapidly between chaotic and regular evolution of a planetary system.
