Secular Resonances in the Dynamics of Objects Moving in LEO–MEO Regions of Near-Earth Orbital Space
Solar System Research, 2021 The paper presents the results of identifying secular resonances that act on objects moving in the LEO–MEO regions. The results were obtained from the processing of data of an extensive numerical experiment on the study of the orbital evolution of ...

Assessing the impact of transient orbital resonances
Physical Review D, 2021 One of the primary sources for the future space-based gravitational wave detector, the Laser Interferometer Space Antenna, are the inspirals of small compact objects into massive black holes in the centres of galaxies.

Chiral orbital lasing in a twisted bilayer metasurface [PDF]
Nature CommunicationsChirality is a fundamental concept in physics, core to many phenomena in nonlinear optics, quantum physics and topological photonics. Photons are intrinsically chiral when carrying spin angular momentum, whereas orbital angular momentum can induce ...

Coupling of Dynamical Tide and Orbital Motion
The Astrophysical JournalThe dynamical tide consists of various waves that can resonate with orbital motion. We test this coupling of the dynamical tide and orbital motion using a simple 2D shallow water model, which can be applied to a rocky planet covered with a thin ocean or ...

Orbital Resonances in the Solar Nebula: Strengths and Weaknesses
Icarus, 1993 A planetesimal moving in the Solar Nebula experiences an aero- dynamic drag which causes its orbit to circularize and shrink. However, resonant perturbations from a protoplanet interior to the planetesimal's orbit ran counteract both the orbital decay ...

Dynamics and Origin of the 2 : 1 Orbital Resonances of the GJ 876 Planets
Astrophysical Journal, 2002 The discovery by Marcy and coworkers of two planets in 2:1 orbital resonance about the star GJ 876 has been supplemented by a dynamical fit to the data by Laughlin & Chambers, which places the planets in coplanar orbits deep in three resonances at the 2 ...

A Six-planet Resonance Chain in K2-138?
The Astrophysical Journal, 2023 The K2-138 system hosts six planets and presents an interesting case study due to its distinctive dynamical structure. Its five inner planets are near a chain of 3/2 two-body mean-motion resonances, while the outermost body (planet g) is significantly ...
