Tides in a body librating about a spin-orbit resonance. Generalisation of the Darwin-Kaula theory
Julien Frouard, Michael Efroimsky
The Darwin-Kaula theory of bodily tides is intended for celestial bodies rotating without libration. We demonstrate that this theory, in its customary form, is inapplicable to a li…
Tidal spin down rates of homogeneous triaxial viscoelastic bodies
Alice C. Quillen, Andrea Kueter-Young, Julien Frouard +1
We use numerical simulations to measure the sensitivity of the tidal spin down rate of a homogeneous triaxial ellipsoid to its axis ratios by comparing the drift rate in orbital se…
Precession Relaxation of Viscoelastic Oblate Rotators
Julien Frouard, Michael Efroimsky
Perturbations of all sorts destabilise the rotation of a small body and leave it in a non-principal spin state. In such a state, the body experiences alternating stresses generated…
Numerical Simulation of Tidal Evolution of a Viscoelastic Body Modelled with a Mass-Spring Network
Julien Frouard, Alice C. Quillen, Michael Efroimsky +1
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 poin…
Forced libration of tidally synchronized planets and moons
Valeri V. Makarov, Julien Frouard, Bryan Dorland
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 stabl…
Spin-orbit evolution of Mercury revisited
Benoit Noyelles, Julien Frouard, Valeri Makarov +1
While it is accepted that the eccentricity of Mercury (0.206) favours entrapment into the 3:2 spin-orbit resonance, open is the question how and when the capture took place. A rece…
Instability zones for satellites of asteroids. The example of the (87) Sylvia system
Julien Frouard, Audrey Compère
We study the stability of the (87) Sylvia system and of the neighborhood of its two satellites. We use numerical integrations considering the non-sphericity of Sylvia, as well as t…
