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:

Coupling between corotation and Lindblad resonances in the presence of secular precession rates
TL;DR: In this paper, the CoraLin model was applied to three recently discovered small Saturnian satellites dynamically linked to Mimas through first order mean motion resonances: Aegaeon, Methone and Anthe.
Journal ArticleDOI
Effects of Turbulence, Eccentricity Damping, and Migration Rate on the Capture of Planets into Mean Motion Resonance
TL;DR: In this article, the authors studied the convergent migration of giant planets and determined the probability that they are captured into mean motion resonance, which depends on the type of resonance, the migration rate, the eccentricity damping rate, and the amplitude of the turbulent fluctuations.

Noncircular features in Saturn’s rings II: The C ring
Philip D. Nicholson,Richard G. French,Colleen A. McGhee-French,Matthew M. Hedman,Essam A. Marouf,Joshua Colwell,K. Lonergan,T. Sepersky +7 more
TL;DR: In this article, a comprehensive survey of sharp-edged features in the C ring of Saturn's C ring is presented, using data from radio and stellar occultation experiments carried out by the Cassini spacecraft over a period of more than five years.

A gap in HD 92945's broad planetesimal disc revealed by ALMA
Sebastian Marino,Sebastian Marino,Ben Yelverton,Mark Booth,Virginie Faramaz,Grant M. Kennedy,Luca Matrà,Mark C. Wyatt +7 more
TL;DR: In this article, the first ALMA observations of HD 92945 at 0.86 mm reveal a gap at about 73 ± 3 au within a broad disc of planetesimals that extends from 50 to 140 au.

Mass loss through the L2 Lagrange point - Application to Main Sequence EMRI
Itai Linial,Re'em Sari +1 more
TL;DR: In this paper, stable mass transfer from the secondary to the primary of an extreme mass ratio binary system was considered, and it was shown that mass leakage occurs through the outer Lagrange point L2, in addition to the usual transfer through L1.
