The theory of secondary resonances in the spin–orbit problem [PDF]
Monthly Notices of the Royal Astronomical Society, 2016 We study the resonant dynamics in a simple one degree of freedom, time dependent Hamiltonian model describing spin-orbit interactions. The equations of motion admit periodic solutions associated with resonant motions, the most important being the synchronous one in which most evolved satellites of the Solar system, including the Moon, are observed ...

The Origin of Jupiter’s Obliquity
The Planetary Science Journal, 2023 The origin of the 3.°12 obliquity of Jupiter’s spin axis to its orbit normal is unknown. Improved estimates of Jupiter’s moment of inertia rule out a previously proposed explanation involving a resonance with the precession of the inclined orbit of ...

Tilting Uranus: Collisions versus Spin–Orbit Resonance
The Planetary Science Journal, 2021 Abstract In this paper, we investigate whether Uranus’s 98° obliquity was a by-product of a secular spin–orbit resonance assuming that the planet originated closer to the Sun. In this position, Uranus’s spin precession frequency is fast enough to resonate with another planet located beyond Saturn.

Collision‐induced spin‐orbit relaxation of highly vibrationally excited NO near 1 K
Natural Sciences, 2022 State‐to‐state scattering studies of vibrationally excited molecules in the cold regime extend inelastic scattering investigations into a new territory. Here, we present differential cross‐sections for superelastic scattering of spin‐orbit excited nitric

Magnetotunneling in resonant tunneling structures with spin − orbit interaction [PDF]
Journal of Applied Physics, 2011 Magnetotunneling spectroscopy of resonant tunneling structures provides information on the nature of the two-dimensional electron gas in the well. We describe a model based on nonequilibrium Green’s functions that allows for a comprehensive study of the density of states, tunneling currents and current spin polarization.

Magnetic Topology in Coupled Binaries, Spin-orbital Resonances, and Flares [PDF]
The Astrophysical Journal, 2021 Abstract We consider topological configurations of the magnetically coupled spinning stellar binaries (e.g., merging neutron stars or interacting star–planet systems). We discuss conditions when the stellar spins and the orbital motion nearly “compensate” each other, leading to very slow overall winding of the coupled magnetic fields ...

Probing evolution of binaries influenced by the spin–orbit resonances [PDF]
Classical and Quantum Gravity, 2014 We evolve isolated comparable mass spinning compact binaries experiencing Schnittman's post-Newtonian spin-orbit resonances in an inertial frame associated with $j_0$, the initial direction of the total angular momentum. We argue that accurate gravitational wave (GW) measurements of the initial orientations of the two spins and orbital angular momentum

Tidal Dissipation Regimes among the Short-period Exoplanets
The Astrophysical Journal Letters, 2023 The efficiency of tidal dissipation provides a zeroth-order link to a planet’s physical properties. For super-Earth and sub-Neptune planets in the range R _⊕ ≲ R _p ≲ 4 R _⊕ , particularly efficient dissipation (i.e., low tidal quality factors) may ...
