Tidal Torques. Ii. Two Derivations of the Despinning-rate Formula
نویسندگان
چکیده
We compare two derivations of a popular formula for the tidal despinning rate, and emphasise that both are strongly limited to the case of a vanishing inclination and a certain (sadly, unrealistic) law of frequency-dependence of the quality factor. One method is based on the MacDonald torque, the other on the Darwin torque. Fortunately, the second approach is general enough to accommodate both a finite inclination and the actual rheology.

Tidal torques . A critical review of some techniques
We review some techniques employed in the studies of torques due to bodily tides, and explain why the MacDonald formula for the tidal torque is valid only in the zeroth order of the eccentricity divided by the quality factor, while its time-average is valid in the first order. As a result, the formula cannot be used for analysis in higher orders of e/Q . This necessitates some corrections in th...

متن کاملTidal Friction and Tidal Lagging. Applicability Limitations of a Popular Formula for the Tidal Torque
Tidal torques play a key role in rotational dynamics of celestial bodies. They govern these bodies’ tidal despinning and also participate in the subtle process of entrapment of these bodies into spin–orbit resonances. This makes tidal torques directly relevant to the studies of habitability of planets and their moons. Our work begins with an explanation of how friction and lagging should be bui...
متن کاملTidal Dissipation Due to Despinning and the Equatorial Ridge on Iapetus
Introduction: The equatorial ridge on Iapetus is a geological anomaly in the solar system. This ridge is 20 km high and spans more than half the circumference of Iapetus [1]. Multiple hypotheses have been suggested for the origin of this ridge including convective upwelling in the underlying ice shell [2], the remains of an early ring system [3], and a giant thrust fault as the satellite contra...
