Tidal 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 کاملThe Equilibrium-Tide Model for Tidal Friction
We derive from first principles equations governing (a) the quadrupole tensor of a star distorted by both rotation and the presence of a companion in a possibly eccentric orbit, (b) a functional form for the dissipative force of tidal friction, based on the concept that the rate of energy loss from a time-dependent tide should be a positive-definite function of the rate of change of the quadrup...
متن کاملSemidiurnal Tidal Motions in the Friction Layer
The obscrved semidiurnal wind in the troposphere at five niid-latmit,ude stations shows a, phase lead over the wind dcduccd from frictionlcss theory, and a smaller amplitude, espccially near the earth’s surface, than the theoretical value. By making use of the obscrved fact that the tidal pressure-dependent (frictionless) wind changes much less rapidly with height than does the observed wiiid i...

متن کاملTidal friction in close - in satellites and exoplanets .
This report is a review of Darwin’s classical theory of bodily tides in which we present the analytical expressions for the orbital and rotational evolution of the bodies and for the energy dissipation rates due to their tidal interaction. General formulas are given which do not depend on any assumption linking the tidal lags to the frequencies of the corresponding tidal waves (except that equa...
