Abstract : If the Moon s spin evolved from faster prograde rates, it could have been captured into a higher spin orbit resonance than the current 1:1 resonance. At the current value of orbital eccentricity, the probability of capture into the 3:2 resonance is as high as 0.6, but it strongly depends on the temperature and average viscosity of theMoon s interior. A warmer, less viscous Moon on a higher eccentricity orbit is even more easily captured into supersynchronous resonances. We discuss…

Contribution to the study of the resonant rotation in the Solar System
This HDR-thesis is devoted to the study of the rotation of the natural satellites of the giant planets and of Mercury. These bodies have a resonant rotation. Most of the natural satellites rotate
Forced libration of tidally synchronized planets and moons
Tidal dissipation of kinetic energy, when it is strong enough, tends to synchronize the rotation of planets and moons with the mean orbital motion, or drive it into long-term stable spin-orbit
DYNAMICAL EVOLUTION AND SPIN-ORBIT RESONANCES OF POTENTIALLY HABITABLE EXOPLANETS. THE CASE OF GJ 667C
GJ 581d is a potentially habitable super-Earth in the multiple system of exoplanets orbiting a nearby M dwarf. We investigate this planet's long-term dynamics with an emphasis on its probable final
Equilibrium rotation of semiliquid exoplanets and satellites
A wide range of exoplanet and exomoon models are characterized by a finite average rigidity and a viscosity much lower than the typical values for terrestrials. Such semiliquid bodies may or may not
Spin-Spin Coupling in the Solar System
The richness of dynamical behavior exhibited by the rotational states of various solar system objects has driven significant advances in the theoretical understanding of their evolutionary histories.
Tidal dissipation in a homogeneous spherical body. II. Three examples: Mercury, Io, and Kepler-10 b
Abstract : In Efroimsky & Makarov (Paper I), we derived from the first principles a formula for the tidal heating rate in a homogeneous sphere, compared it with the previously used formulae, and
Magnetic properties of Proxima Centauri b analogues
The Onset of Chaos in Permanently Deformed Binaries from Spin–Orbit and Spin–Spin Coupling
Permanently deformed objects in binary systems can experience complex rotation evolution, arising from the extensively studied effect of spin–orbit coupling as well as more nuanced dynamics arising
Tidal Dissipation in a Homogeneous Spherical Body. I. Methods
A formula for the tidal dissipation rate in a spherical body is derived from first principles to correct some mathematical inaccuracies found in the literature. The development is combined with the
Numerical simulation of tidal evolution of a viscoelastic body modelled with a mass-spring network
We use a damped mass-spring model within an N-body code to simulate the tidal evolution of the spin and orbit of a self-gravitating viscoelastic spherical body moving around a point-mass perturber.

Evidence for a Past High-Eccentricity Lunar Orbit
TLDR
Calculations show how past high-eccentricity orbits can account for the moment differences, represented by the low-order lunar gravity field and libration parameters, and suggest that the Moon may have once been in a 3:2 resonance of orbit period to spin period, similar to Mercury's present state.
No pseudosynchronous rotation for terrestrial planets and moons
We reexamine the popular belief that a telluric planet or satellite on an eccentric orbit can, outside a spin-orbit resonance, be captured in a quasi-static tidal equilibrium called pseudosynchronous
Resonances in the Early Evolution of the Earth-Moon System
Most scenarios for the formation of the Moon place the Moon near Earth in low-eccentricity orbit in the equatorial plane of Earth. We examine the dynamical evolution of the Earth-Moon system from
Tidal decay of close planetary orbits
The 4.2-day orbit of the newly discovered planet around 51~Pegasi is formally unstable to tidal dissipation. However, the orbital decay time in this system is longer than the main-sequence lifetime

The dynamical evolution of terrestrial planets resembling Mercury in the vicinity of spin-orbit resonances is investigated using comprehensive harmonic expansions of the tidal torque taking into

▪ Abstract The giant impact theory is the leading hypothesis for the origin of the Moon. This review focuses on dynamical aspects of an impact-induced lunar formation, in particular those areas that

Making the Moon from a Fast-Spinning Earth: A Giant Impact Followed by Resonant Despinning
TLDR
Computer simulations show that a giant impact on early Earth could lead to a Moon with a composition similar to Earth’s, and shows that a faster-spinning early Earth-Moon system can lose angular momentum and reach the present state through an orbital resonance between the Sun and Moon.
