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:

Long-term stability of the HR 8799 planetary system without resonant lock
TL;DR: In this paper, the authors simulate planetary systems similar to the HR 8799 planetary system, exploring the parameter space in separation between the orbits, planetary masses and distance from the Sun to the star.
Journal ArticleDOI
On the dynamics of resonant super-Earths in disks with turbulence driven by stochastic forcing
TL;DR: In this paper, the authors investigated the evolution of a system of two super-Earths embedded in a turbulent protoplanetary disk and examined whether resonant trapping can be maintained in the presence of turbulence and how this depends on the amplitude of the stochastic density fluctuations in the disk.

Tidal pull of the Earth strips the proto-Moon of its volatiles
Sébastien Charnoz,Paolo A. Sossi,Y-N Lee,Julien Siebert,Ryuki Hyodo,L. Allibert,Francesco C. Pignatale,Maylis Landeau,Apurva Oza,Frédéric Moynier +9 more
TL;DR: In this article, the authors investigate a simple process, wherein the Earth's tidal pull promotes intense hydrodynamic escape from the liquid surface of a molten proto-Moon assembling at 3-6 Earth radii.

The role of secular resonances on trojans of the terrestrial planets
R. Brasser,Harry Lehto +1 more
TL;DR: In this paper, the authors investigated the role of terrestrial-planet trojans in tadpole motion for 5 Myr in the inclination range i ≤ 90° and found no stable trojan motion when i > 40°.

A numerical study of powered Swing-Bys around the Moon
TL;DR: In this article, the authors studied swing-by maneuvers combined with the application of an impulse at the spacecraft periapsis passage, and showed that an angle α near 20° gives the best solution to maximize the energy gains for the situation where the periapis distance is 1.1 Moon's radius and Ψ = 90 °.
