Q in the solar system

  title={Q in the solar system},
  author={P. Goldreich and S. Soter},
Abstract Secular changes brought about by tidal friction in the solar system are reviewed. The presence or absence of specific changes is used to bound the values of Q (the specific dissipation function) appropriate for the planets and satellites. It is shown that the values of Q separate sharply into two groups. Values in the range from 10 to 500 are found for the terrestrial planets and satellites of the major planets. On the other hand, Q for the major planets is always larger than 6 × 10 4… Expand

Tidal Dissipation in the Solid Cores of the Major Planets
Abstract If the orbital resonances in the Jovian and Saturnian satellite systems are the result of orbital evolution due to tidal dissipation then the present rates of energy dissipation ( E dot )Expand
On the origin of the solar system, I
The principal dynamical properties of the planetary and satellite systems listed in Section 2 require these bodies to have condensed in highly-flattened nebulae which provided the dissipation forcesExpand
Tides in Planetary Systems
The Solar system is the seat of many interactions between the Sun, the planets and their natural satellites. Moreover, since 1995, a large number of extrasolar planetary systems has been discoveredExpand
Secular Effects of Tidal Damping in Compact Planetary Systems
We describe the long-term evolution of compact systems of terrestrial planets, using a set of simulations that match the statistical properties of the observed exoplanet distribution. The evolutionExpand
Tidal evolution of close-in extra-solar planets
Abstract The distribution of eccentricities e of extra-solar planets with semi-major axes a > 0.2 AU is very uniform, and values for e are generally large. For a < 0.2 AU, eccentricities are muchExpand
A co-accretional model of satellite formation
Abstract Numerical calculation of a simple accretion model including the effects of tidal friction indicate that coformation is tenable only if the planet's Q is less than about 103. The parameterExpand
Tidal interactions of close-in extrasolar planets: The OGLE cases
Close-in extrasolar planets experience extreme tidal interactions with their host stars. This may lead to a reduction of the planetary radius and a spin-up of stellar rotation. Tidal interactionsExpand
Tidal evolution of the Kepler-10 system
We investigate by numerical methods the tidal evolution of the Kepler-10 system, which consists of an inner rocky planet and an outer terrestrial planet, by considering various initial eccentricityExpand
On the Radii of Extrasolar Giant Planets
We have computed evolutionary models for extrasolar planets that range in mass from 0.1MJ to 3.0MJ and that range in equilibrium temperature from 113 to 2000 K. We present four sequences of models,Expand
Tides in Planetary Systems and in Multiple Stars: a Physical Picture
Many stars belong to close binary or multiple stellar systems. Moreover, since 1995, a large number of extrasolar planetary systems have been discovered where planets can orbit very close to theirExpand


Tidal De-spin of Planets and Satellites
RECENTLY, Peale and Gold1 have shown that the non-synchronous rotation of Mercury is likely to be a consequence of tidal friction. They point out that in an eccentric orbit the spin of an axiallyExpand
Rotation of the Planet Mercury
SOLAR tidal friction must be an intense effect for Mercury, and it must be expected that the planet's spin would have relaxed from any original value to one that is under the control of this effectExpand
The internal constitutions of the inner planets and the moon
The internal structures of the moon, Mars, Venus, and Mercury are examined in the light of what is known about the constitution of the earth. The gravitational figure of the earth as obtained fromExpand
The luni-tidal interval in Mars and the secular acceleration of Phobos
Abstract Phobos, the inner satellite of Mars, appears to perform a secular acceleration in longitude. The cause of this acceleration has not, as yet, been satisfactorily explained. The possibility ofExpand

Owing to the fact that the image of Pluto, as seen from the earth, is essentially stellar, it has not been possible to determine its period of rotation by observations of surface features or byExpand
