New results on orbital resonances. [PDF]
Proc Int Astron Union, 2021 AbstractPerturbative analyses of planetary resonances commonly predict singularities and/or divergences of resonance widths at very low and very high eccentricities. We have recently re-examined the nature of these divergences using non-perturbative numerical analyses, making use of Poincaré sections but from a different perspective relative to ...

Orbital symmetry fingerprints for magnetic adatoms in graphene [PDF]
New Journal of Physics, 2014 In this paper, we describe the formation of local resonances in graphene in the presence of magnetic adatoms containing localized orbitals of arbitrary symmetry, corresponding to any given angular momentum state. We show that quantum interference effects

Secondary resonances of co-orbital motions [PDF]
, 2007 The size distribution of the stability region around the Lagrangian point L4 is investigated in the elliptic restricted three-body problem as the function of the mass parameter and the orbital eccentricity of the primaries.

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 ...

Dissipative Capture of Planets into First-order Mean-motion Resonances
The Astrophysical Journal Letters, 2023 The emergence of orbital resonances among planets is a natural consequence of the early dynamical evolution of planetary systems. While it is well established that convergent migration is necessary for mean-motion commensurabilities to emerge, recent ...

GPS Satellites Orbits: Resonance [PDF]
Mathematical Problems in Engineering, 2009 The effects of perturbations due to resonant geopotential harmonics on the semimajor axis of GPS satellites are analyzed. For some GPS satellites, secular perturbations of about 4 m/day can be obtained by numerical integration of the Lagrange planetary equations considering in the disturbing potential the main secular resonant coefficients.

Enhanced Black Hole Mergers in Active Galactic Nucleus Disks due to Precession-induced Resonances
The Astrophysical Journal, 2023 Recent studies have shown that active galactic nucleus (AGN) disks can host sources of gravitational waves. Compact binaries can form and merge in AGN disks through their interactions with the gas and other compact objects in the disk.

Mie Resonance Engineering in Two Disks
Photonics, 2021 Recently the recipes to achieve the high-Q subwavelength resonances in an isolated dielectric disk have been reported based on avoided crossing (anticrossing) of the TE resonances under variation of the aspect ratio of the disk.

Long-term Stability of Planetary Systems Formed from a Transitional Disk
The Astrophysical Journal, 2023 Transitional disks are protoplanetary disks with large and deep central holes in the gas, possibly carved by young planets. Dong & Dawson simulated systems with multiple giant planets that were capable of carving and maintaining such gaps during the disk

exoMMR: A New Python Package to Confirm and Characterize Mean Motion Resonances
The Astronomical Journal, 2023 The study of orbital resonances allows for the constraint of planetary properties of compact systems. We can predict a system’s resonances by observing the orbital periods of the planets, as planets in or near mean motion resonance (MMR) have period ...
