Tidal dissipation in stars and giant planets

GI Ogilvie - Annual Review of Astronomy and Astrophysics, 2014 - annualreviews.org
Astrophysical fluid bodies that orbit close to one another induce tidal distortions and flows
that are subject to dissipative processes. The spin and orbital motions undergo a coupled …

Tidal dissipation in evolving low-mass and solar-type stars with predictions for planetary orbital decay

AJ Barker - Monthly Notices of the Royal Astronomical Society, 2020 - academic.oup.com
We study tidal dissipation in stars with masses in the range 0.1–1.6 M⊙ throughout their
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 …

Strong tidal dissipation in Io and Jupiter from astrometric observations

V Lainey, JE Arlot, Ö Karatekin, T Van Hoolst - Nature, 2009 - nature.com
Io is the volcanically most active body in the Solar System and has a large surface heat flux,,.
The geological activity is thought to be the result of tides raised by Jupiter, but it is not known …

Resonance locking as the source of rapid tidal migration in the Jupiter and Saturn moon systems

J Fuller, J Luan, E Quataert - Monthly Notices of the Royal …, 2016 - academic.oup.com
The inner moons of Jupiter and Saturn migrate outwards due to tidal energy dissipation
within the planets, the details of which remain poorly understood. We demonstrate that …

A close-in giant planet escapes engulfment by its star

M Hon, D Huber, NZ Rui, J Fuller, D Veras… - Nature, 2023 - nature.com
When main-sequence stars expand into red giants, they are expected to engulf close-in
planets,,,–. Until now, the absence of planets with short orbital periods around post …

Tidal dissipation in rotating solar-type stars

GI Ogilvie, DNC Lin - The Astrophysical Journal, 2007 - iopscience.iop.org
We calculate the excitation and dissipation of low-frequency tidal oscillations in uniformly
rotating solar-type stars. For tidal frequencies smaller than twice the spin frequency, inertial …

Foretellings of Ragnarök: world-engulfing asymptotic giants and the inheritance of white dwarfs

AJ Mustill, E Villaver - The Astrophysical Journal, 2012 - iopscience.iop.org
The search for planets around white dwarf stars, and evidence for dynamical instability
around them in the form of atmospheric pollution and circumstellar disks, raises questions …

STRONG TIDAL DISSIPATION IN SATURN AND CONSTRAINTS ON ENCELADUS'THERMAL STATE FROM ASTROMETRY

V Lainey, Ö Karatekin, J Desmars… - The Astrophysical …, 2012 - iopscience.iop.org
Tidal interactions between Saturn and its satellites play a crucial role in both the orbital
migration of the satellites and the heating of their interiors. Therefore, constraining the tidal …
