Origin and Evolution of Enceladus's Tidal Dissipation. [PDF]

Space Sci Rev, 2023
AbstractEnceladus possesses a subsurface ocean beneath a conductive ice shell. Based on shell thickness models, the estimated total conductive heat loss from Enceladus is 25–40 GW; the measured heat output from the South Polar Terrain (SPT) is 4–19 GW. The present-day SPT heat flux is of order $100\text{ mW}\,\text{m}^{-2}$ 100

Understanding tidal dissipation in gaseous giant planets from their core to their surface [PDF]

EPJ Web of Conferences, 2015
Tidal dissipation in planetary interiors is one of the key physical mechanisms that drive the evolution of star-planet and planet-moon systems. Tidal dissipation in planets is intrinsically related to their internal structure.

EMPIRICAL TIDAL DISSIPATION IN EXOPLANET HOSTS FROM TIDAL SPIN-UP. [PDF]

Astron J, 2018
Abstract Stars with hot Jupiters (HJs) tend to rotate faster than other stars of the same age and mass. This trend has been attributed to tidal interactions between the star and planet. A constraint on the dissipation parameter follows from the assumption that tides have ...

Strong Tidal Dissipation at Uranus?

The Planetary Science Journal, 2023
Geophysical estimates of paleo heat fluxes on the Uranian moons Miranda and Ariel are in the range of 25–75 mW m ^−2 . For a canonical Uranus dissipation factor Q = 18,000, expected equilibrium tidal heating rates for these satellites are less than 6 mW ...

Tidal Dissipation in WASP-12 [PDF]

The Astrophysical Journal Letters, 2017
WASP-12 is a hot Jupiter system with an orbital period of $P= 1.1\textrm{ day}$, making it one of the shortest-period giant planets known. Recent transit timing observations by Maciejewski et al. (2016) and Patra et al.

On the Tidal Dissipation of Obliquity [PDF]

The Astrophysical Journal, 2013
We investigate tidal dissipation of obliquity in hot Jupiters. Assuming an initial random orientation of obliquity and parameters relevant to the observed population, the obliquity of hot Jupiters does not evolve to purely aligned systems.

Lateral melt variations induce shift in Io’s peak tidal heating [PDF]

Nature Communications
The innermost Galilean moon, Io, exhibits widespread tidally-driven volcanism. Monitoring of its volcanoes has revealed that they are not homogeneously distributed across its surface: volcanic activity is higher at low latitudes and peaks east of the sub-

Tidal dissipation in rotating giant planets

The Astrophysical Journal, 2003
[Abridged] Tides may play an important role in determining the observed distributions of mass, orbital period, and eccentricity of the extrasolar planets.

Tidal Dissipation Regimes among the Short-period Exoplanets

The Astrophysical Journal Letters, 2023
The efficiency of tidal dissipation provides a zeroth-order link to a planet’s physical properties. For super-Earth and sub-Neptune planets in the range R _⊕ ≲ R _p ≲ 4 R _⊕ , particularly efficient dissipation (i.e., low tidal quality factors) may ...

Tidal Migration of Exoplanets around M Dwarfs: Frequency-dependent Tidal Dissipation

The Astrophysical Journal
The orbital architectures of short-period exoplanet systems are shaped by tidal dissipation in their host stars. For low-mass M dwarfs whose dynamical tidal response comprises a dense spectrum of inertial modes at low frequencies, resolving the frequency
