Tidal dissipation in rotating giant planets
Many extrasolar planets orbit sufficiently close to their host stars that significant tidal interactions can be expected, resulting in an evolution of the spin and orbital properties of the planets. The accompanying dissipation of energy can also be an important source of heat, leading to the inflation of short-period planets and even mass loss through Roche-lobe overflow. Tides may therefore p...
متن کاملTidal pattern instabilities on multi-moon planets
The equilibrium tide-generating forces in the lunar orbital plane of a planet of radius R are calculated for the case of N moons of mass Mi orbiting the planet at instantaneous polar coordinates (Di, αi). For the case of a single moon, there are only two high tides. For the case of two moons, it is found that there can exist a critical lunar orbital distance at which two high tides become unsta...
متن کاملViscoelastic tidal dissipation in giant planets and formation of hot Jupiters through high-eccentricity migration
We study the possibility of tidal dissipation in the solid cores of giant planets and its implication for the formation of hot Jupiters through high-eccentricity migration. We present a general framework by which the tidal evolution of planetary systems can be computed for any form of tidal dissipation, characterized by the imaginary part of the complex tidal Love number, Im[k̃2(ω)], as a functi...
متن کاملTidal Heating of Extrasolar Planets
Extrasolar planets close to their host stars have likely undergone significant tidal evolution since the time of their formation. Tides probably dominated their orbital evolution once the dust and gas cleared away, and as the orbits evolved there was substantial tidal heating within the planets. The tidal heating history of each planet may have contributed significantly to the thermal budget go...
متن کاملTidal Evolution of Close-in Extrasolar Planets
The distribution of eccentricities e of extrasolar planets with semimajor axes a > 0:2 AU is very uniform, and values for e are relatively large, averaging 0.3 and broadly distributed up to near 1. For a < 0:2 AU, eccentricities are much smaller (most e < 0:2), a characteristic widely attributed to damping by tides after the planets formed and the protoplanetary gas disk dissipated.Most previou...
