Surprising Spin–Orbit Resonances of Rocky Planets
Astrophysical JournalRecent works suggest that, in multiplanetary systems, a close-in exoplanet can sometimes avoid becoming tidally locked to its host star if it is captured into a secular spin–orbit resonance with a companion planet. In such a resonance, the planet remains

Bodily tides near spin–orbit resonances [PDF]
Celestial Mechanics and Dynamical Astronomy, 2012 Spin-orbit coupling can be described in two approaches. The method known as "the MacDonald torque" is often combined with an assumption that the quality factor Q is frequency-independent. This makes the method inconsistent, because the MacDonald theory tacitly fixes the rheology by making Q scale as the inverse tidal frequency.

Secular Spin–Orbit Resonances of Black Hole Binaries in AGN Disks
The Astrophysical Journal, 2023 The spin–orbit misalignment of stellar-mass black hole (sBH) binaries provides important constraints on the formation channels of merging sBHs. Here, we study the role of secular spin–orbit resonance in the evolution of an sBH binary component around a ...

Second-Order Perturbation Theory for Spin-Orbit Resonances [PDF]
Astronomical Journal, 2005 We implement Lie transform perturbation theory to second order for the planar spin-orbit problem. The perturbation parameter is the asphericity of the body, with the orbital eccentricity entering as an additional parameter. We study first and second order resonances for different values of these parameters.

Dynamical Structures Associated with High-Order and Secondary Resonances in the Spin–Orbit Problem
Astronomical JournalIn our solar system, spin–orbit resonances are common under Sun–planet, planet–satellite, and binary asteroid configurations. In this work, high-order and secondary spin–orbit resonances are investigated by taking numerical and analytical approaches ...

Astronomical Journal, 2017 Abstract By considering a varying mutual orbit between the two bodies in a binary minor planet system, modified models for the spin–orbit, spin–spin, and spin–orbit–spin resonances are given. For the spin–orbit resonances, our study shows that the resonance center changes with the mass ratio and the mutual distance between the two bodies,

Strength of higher-order spin-orbit resonances [PDF]
Physical Review E, 2004 When polarized particles are accelerated in a synchrotron, the spin precession can be periodically driven by Fourier components of the electromagnetic fields through which the particles travel. This leads to resonant perturbations when the spin-precession frequency is close to a linear combination of the orbital frequencies.

Tilting Ice Giants with a Spin–Orbit Resonance [PDF]
The Astrophysical Journal, 2020 Abstract Giant collisions can account for Uranus’s and Neptune’s large obliquities, yet generating two planets with widely different tilts and strikingly similar spin rates is a low-probability event. Trapping into a secular spin–orbit resonance, a coupling between spin and orbit precession frequencies, is a promising alternative, as it ...

Spin–orbit-driven ferromagnetic resonance [PDF]
Nature Nanotechnology, 2011 Ferromagnetic resonance is the most widely used technique for characterizing ferromagnetic materials. However, its use is generally restricted to wafer-scale samples or specific micro-magnetic devices, such as spin valves, which have a spatially varying magnetization profile and where ferromagnetic resonance can be induced by an alternating current ...
