Effective resonant stability of Mercury
- Physics, Geology
- 2015
Mercury is the unique known planet that is situated in a 3:2 spin-orbit resonance nowadays. Observations and models converge to the same conclusion: the planet is presently deeply trapped in the…
Revisiting the capture of Mercury into its 3:2 spin-orbit resonance
- PhysicsProceedings of the International Astronomical Union
- 2014
Abstract We simulate the despinning of Mercury, with or without a fluid core, and with a frequency-dependent tidal model employed. The tidal model incorporates the viscoelastic (Maxwell) rebound at…
Periodic and quasi-periodic attractors for the spin-orbit evolution of Mercury with a realistic tidal torque
- Physics

In this paper, we make a detailed study of the spin-orbit dynamics of Mercury, as predicted by the realistic model which has been recently introduced in a series of papers mainly by Efroimsky and…
Spin-orbital Tidal Dynamics and Tidal Heating in the TRAPPIST-1 Multiplanet System
- Physics, Geology
- 2018
We perform numerical simulations of the TRAPPIST-1 system of seven exoplanets orbiting a nearby M dwarf, starting with a previously suggested stable configuration. The long-term stability of this…
Rotation and figure evolution in the creep tide theory: a new approach and application to Mercury
- PhysicsCelestial Mechanics and Dynamical Astronomy
- 2019
This paper deals with the rotation and figure evolution of a planet near the 3/2 spin–orbit resonance and the exploration of a new formulation of the creep tide theory (Folonier et al. in Celest Mech…
Thermal and Orbital Evolution of Low-mass Exoplanets
- Physics, GeologyThe Astrophysical Journal
- 2020
The thermal, orbital, and rotational dynamics of tidally loaded exoplanets are interconnected by intricate feedback. The rheological structure of the planet determines its susceptibility to tidal…
Steady state obliquity of a rigid body in the spin–orbit resonant problem: application to Mercury
- Physics

We investigate the stable Cassini state 1 in the p : q spin–orbit resonant problem. Our study includes the effect of the gravitational potential up to degree and order 4 and p : q spin–orbit…
Averaged model to study long-term dynamics of a probe about Mercury
- Physics, Geology
- 2018
This paper provides a method for finding initial conditions of frozen orbits for a probe around Mercury. Frozen orbits are those whose orbital elements remain constant on average. Thus, at the same…
TIDAL EVOLUTION OF ASTEROIDAL BINARIES. RULED BY VISCOSITY. IGNORANT OF RIGIDITY
- Physics
- 2015
This is a pilot paper serving as a launching pad for study of orbital and spin evolution of binary asteroids. The rate of tidal evolution of asteroidal binaries is defined by the dynamical Love…
Final spin states of eccentric ocean planets

Mercury's capture into the 3/2 spin-orbit resonance as a result of its chaotic dynamics
- Physics, GeologyNature
- 2004
It is shown that the chaotic evolution of Mercury's orbit can drive its eccentricity beyond 0.325 during the planet's history, which very efficiently leads to its capture into the 3/2 resonance.

We investigate the spin-orbital evolution of the potentially habitable super-Earth GJ 667Cc in the multiple system of at least two exoplanets orbiting a nearby M dwarf. The published radial…
A pre-Caloris synchronous rotation for Mercury
- Physics, Geology

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…
Mercury's core - The effect of obliquity on the spin-orbit constraints

In an earlier paper by the authors (Peale and Boss, 1977), rather severe constraints were placed on the properties of a Mercurian liquid core and certain other dynamical characteristics of the planet…
A simple model of the chaotic eccentricity of Mercury
- Physics, Geology

Mercury’s eccentricity is chaotic and can increase so much that collisions with Venus or the Sun become possible. This chaotic behavior results from an intricate network of secular resonances, but in…
Existence of collisional trajectories of Mercury, Mars and Venus with the Earth
- Physics, GeologyNature
- 2009
Numerical simulations of the evolution of the Solar System over 5 Gyr, including contributions from the Moon and general relativity find that one per cent of the solutions lead to a large increase in Mercury’s eccentricity—an increase large enough to allow collisions with Venus or the Sun.
