Tidal dissipation in giant planets

J Fuller, T Guillot, S Mathis, C Murray - Space Science Reviews, 2024 - Springer
Tidal interactions between moons and planets can have major effects on the orbits, spins,
and thermal evolution of the moons. In the Saturn system, tidal dissipation in the planet …

Orbital decay of short-period exoplanets via tidal resonance locking

L Ma, J Fuller - The Astrophysical Journal, 2021 - iopscience.iop.org
A large fraction of known exoplanets have short orbital periods where tidal excitation of
gravity waves within the host star causes the planets' orbits to decay. We study the effects of …

Convective turbulent viscosity acting on equilibrium tidal flows: new frequency scaling of the effective viscosity

CD Duguid, AJ Barker, CA Jones - Monthly Notices of the Royal …, 2020 - academic.oup.com
Turbulent convection is thought to act as an effective viscosity (ν E) in dam** tidal flows in
stars and giant planets. However, the efficiency of this mechanism has long been debated …

Tidal dissipation due to the elliptical instability and turbulent viscosity in convection zones in rotating giant planets and stars

NB de Vries, AJ Barker… - Monthly Notices of the …, 2023 - academic.oup.com
Tidal dissipation in star–planet systems can occur through various mechanisms, among
which is the elliptical instability. This acts on elliptically deformed equilibrium tidal flows in …
