Tidal dissipation in Mars: where and how?
نویسندگان
چکیده
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 the mantle, atmospheric tides, and dissipation within a crustal aquifer system. We also discuss how future observations may better constrain this process.

Improved estimate of tidal dissipation within Mars from MOLA observations of the shadow of Phobos
[1] We report on new observations of the orbital position of Phobos, the innermost natural satellite of Mars, and show that these observations provide an improved estimate of the rate of tidal dissipation within Mars. The observations were made with the Mars Orbiter Laser Altimeter instrument on the Mars Global Surveyor spacecraft. The secular acceleration in along-track orbital motion is conve...
متن کاملDissipation at tidal and seismic frequencies in a melt-free, anhydrous Mars
The measured inwards motion of Phobos provides a constraint on the tidal dissipation factor, Q, within Mars. We model viscoelastic dissipation inside a convective Mars using a modified Burgers model based on laboratory experiments on anhydrous, melt-free olivine. The model tidal Q is highly sensitive to the mantle potential temperature and grain size assumed, but relatively insensitive to the b...
متن کاملNon-chaotic Obliquity Variations of Mars
Introduction: In the absence of energy dissipation, obliquity variations of Mars would likely be chaotic. However, relatively small amounts of dissipation suffice to suppress the chaotic variations. Tidal dissipation within Mars, as constrained by the observed evolution of the orbit of Phobos, appears sufficient to regularize the obliquity variations. If Mars has a fluid core, viscous core-mant...
متن کاملOrigin of Tidal Dissipation in Jupiter: Ii. the Value of Q
Having studied the structure and properties of inertial-modes in a neutrally buoyant, uniformly rotating sphere (Wu 2004), we examine here their effect on tidal dissipation in Jupiter. The rate of tidal dissipation caused by resonantly excited inertial-modes depends on the following three parameters: how well coupled inertial-modesare to the tidal potential, how strongly dissipated inertial-mod...
