The Dynamics of Planetary Rings

Annual Review of Astronomy and Astrophysics, 1982
The discovery of ring systems around Uranus and Jupiter, and the Pioneer and Voyager spacecraft observations of Saturn, have shown that planetary rings are both more common and more complex than previously suspected. These ring systems, interesting in their own right, also serve as prototypes for more massive disk systems such as accretion disks ...

Dynamic modelling of wheeled planetary rovers

Proceedings of 2011 International Conference on Electronic & Mechanical Engineering and Information Technology, 2011
A dynamic model for wheeled planetary rovers based on the pseudo-coordinates approach is presented. The model allows any number of wheels and different types of suspensions to be considered and can used for rovers steered by steering wheels or by slip steering.

Planetary ring dynamics

Philosophical Transactions of the Royal Society of London. Series A: Physical and Engineering Sciences, 1994
Abstract The dynamics of planetary rings are reviewed in the light of data derived from the recent spacecraft missions to the outer planets. It is shown that although the ring systems of Jupiter, Saturn, Uranus and Neptune display a great diversity of phenomena and dynamical structures, they have many features and problems in common ...

Dynamics of Planetary Reductor with Turbulent Damping

International Journal of Nonlinear Sciences and Numerical Simulation, 2001
Summary: The nonlinear dynamic system of a planetary reductor with turbulent damping is studied. A simplified nonlinear dynamic model is presented, and the turbulent damping is assumed to be proportional to the square of angular velocity of rotation cog-wheel.

The dynamics of planetary magnetospheres

Planetary and Space Science, 2001
Abstract Mercury, Earth, Jupiter, Saturn, Uranus, Neptune, and the moon, Ganymede, have presently-active internal dynamos while Venus, Mars, at least two of the Galilean moons, the Earth's moon, comets and asteroids do not. These active dynamos produce magnetic fields that have sufficient strength to stand off the pressure of the exterior plasma ...

Dynamic Habitability Of Extrasolar Planetary Systems

Celestial Mechanics and Dynamical Astronomy, 2005
In this paper, we estimate the likelihood to find habitable Earth-like planets on stable orbits for the extrasolar planetary systems ee Eridani, 55 Cancri, 47 Ursae Majoris, and ρ Coronae Borealis and provide a new tool to assess habitability of extrasolar planetary systems.
