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,

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

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 Circularization of Binaries by Resonance Locking. I. The Importance of the Pre-main Sequence

JJ Zanazzi, Y Wu - The Astronomical Journal, 2021 - iopscience.iop.org
Although tidal dissipation in binary stars has been studied for over a century, theoretical
predictions have yet to match the observed properties of binary populations. This work …

The effects of non-linearities on tidal flows in the convective envelopes of rotating stars and planets in exoplanetary systems

A Astoul, AJ Barker - Monthly Notices of the Royal Astronomical …, 2022 - academic.oup.com
In close exoplanetary systems, tidal interactions drive orbital and spin evolution of planets

Tidal dissipation in stratified and semi-convective regions of giant planets

CM Pontin, AJ Barker, R Hollerbach - The Astrophysical Journal, 2023 - iopscience.iop.org
We study how stably stratified or semi-convective layers alter the tidal dissipation rates
associated with the generation of internal waves in planetary interiors. We consider if these …
