Melting of io by tidal dissipation.
The dissipation of tidal energy in Jupiter's satellite Io is likely to have melted a major fraction of the mass. Consequences of a largely molten interior may be evident in pictures of Io's surface returned by Voyager I.
متن کاملTidal dissipation in Mars: where and how?
Introduction: The orbit of Phobos is secularly decaying at a rate which implies that Mars is highly dissipative; even more so than Earth’s mantle. Most tidal dissipation on Earth occurs within the oceans. Where and how the tidal energy dissipation occurs within Mars is not presently well constrained. We examine several alternatives, including a uniformly warm mantle, a partial melt zone within ...
متن کاملTidal Dissipation in Rotating Solar-type Stars
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 waves are excited in the convective envelope and are dissipated by turbulent viscosity. Enhanced dissipation occurs over the entire frequency range rather than in a series of very narrow resonant peaks, and ...
متن کاملMars Thermal Evolution: Aided by Tidal Dissipation?
Introduction: Early models of accretion of Mars [1] suggested long time scales and led to assumed cold post-accretion initial temperatures [2]. But later accretion models [3] gave much shorter time scales and led to the general acceptance of a hot Mars heated by the kinetic energy of impacting planetesimals. Evidence from isotopic studies also seems to require early melting; in particular, Hf-W...
متن کاملTidal dissipation at arbitrary eccentricity and obliquity
Expressions for tidal dissipation in a body in synchronous rotation at arbitrary orbital eccentricity and obliquity are derived. The rate of tidal dissipation for a synchronously rotating body is compared to that in a body in asymptotic nonsynchronous rotation. © 2007 Elsevier Inc. All rights reserved.
