TLDR
In this paper, the authors separate the tidal evolution of a planet-satellite system with zero eccentricity in two phases: phase 1, from the formation of the system to satellite's corotation (satellite's CORotation means that its spin angular velocity equals the orbital angular velocity).Abstract:
We separate the tidal evolution of a planet-satellite system with zero eccentricity in two phases:phase 1—from the formation of the system to satellite's corotation (satellite's corotation means that its spin angular velocity equals the orbital angular velocity);phase 2—after satellite's corotation. We study the planet-satellite system during phase 1 with Darwin's graphical method and obtain an upper limit to satellite'sQ which discloses whether or not it is corotating. Moreover we obtain some qualitative information about the future evolution of the corotating satellites. The present work does not give any new result for the Earth-Moon case and for the Neptune-Triton case.read more

Tidal Evolution and the Pluto-Charon System
TL;DR: In this paper, the authors analyzed the system formed by Pluto and its satellite Charon from the point of view of the theory of tidal evolution, and the singular feature of the system, i.e., the configuration of complete synchronism which has been suggested by the available data, was found to represent the stable end product of the evolution.

On the shape of Amalthea
TL;DR: In this article, the authors tried to fit these data into the equations for an approximately equipotential surface and conclude that its density must be 1.8g cm−3 if it is formed on a synchronous orbit around Jupiter.

The Shape of Small Solar System Bodies: Gravitational Equilibrium vs. Solid-State Interactions
TL;DR: In this paper, the shape of small planetary satellites and asteroids is compared with the theory of equilibrium figures for self-gravitating masses, which allows to obtain interesting informations on the structure, density and strenght of these bodies.

An explanation for the light curve of Jupiter's and Saturn's satellites
TL;DR: In this paper, the authors assume that during the final phase of the satellite accumulation process, the surfaces were subjected to a heavy meteoroidal bombardment by the residual bodies in the circumplanetary protosatellite swarms.

A tidal hypothesis about the origin of planetary rotation
TL;DR: In this article, the authors assume that the solar tidal action on accreting protoplanets forced them to corotation, and assuming a subsequent conservation of spin angular momentum, they can easily get a rough explanation of the actual rotation periods of the planets, the trend toward small inclination angles for the rotation axes, and the existence of a relation between rotational angular momenta and planetary masses similar to the empirical ones due to McDonald (1964).

TL;DR: Tidal dissipation function in solar system, examining cases having appreciable evolution since origin of planets and satellites as discussed by the authors, examined cases having interesting evolution since the discovery of the solar system.

The Rotation of the Planet Mercury
TL;DR: In this article, the authors used radar data and a model developing superharmonic resonance to study the solar rotational period as consequence of solar torques and equatorial asymmetry.

An explanation of the light curve of Iapetus
A. F. Cook,Fred A. Franklin +1 more
TL;DR: In this article, a simple explanation for the large-amplitude (∼ 2 mag) periodic light curve of Saturn's satellite Iapetus was proposed, which, as the light curve shows, apparently rotates synchronously.
