evolution, including turbulent effective viscosity acting on equilibrium tides and inertial …

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 damping 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 …

Tidal dissipation due to inertial waves can explain the circularization periods of solar-type binaries

AJ Barker - The Astrophysical Journal Letters, 2022 - iopscience.iop.org
Tidal dissipation is responsible for circularizing the orbits and synchronizing the spins of
