Planetary Fission Events: Dynamical Constraints
Nature, 1970PLANETARY fission has been proposed recently as a factor in the distribution of mass and density among the “terrestrial” planets. In particular, it has been suggested because of their similar densities that the Moon and Mars were once part of the Earth (see McCrea1 and Lyttleton2, although Lyttleton gave equal support to a capture hypothesis for the ...

Planetary rings are found around all four giant planets of our solar sys- tem. These collisional and highly flattened disks exhibit a whole wealth of physical processes involving microscopic dust grains, as well as meter-sized boulders. These processes, together with ring composition, can help to understand better the for- mation and evolution of proto-

Dynamics of Planetary Approach
1968For a precise interplanetary orbit, the n-body problem including the sun and the nearby planets must be solved. However, for a preliminary analysis the method of patched-conics based on three distinct two-body problems is generally satisfactory. The orbit will then consist of a planetocentric segment near the departure planet, a heliocentric segment ...

The high density of radiation in the L α line of hydrogen should be evaluated as the most characteristic property of a PN. This is one of the basic conclusions brought out by the radiative transfer theory for PNs (Chap. 11). As for the flux of Lα radiation, it is different in various layers of the nebula.

The dynamics of planetary magnetospheres
Planetary and Space Science, 2001Abstract 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 ...

Tropopause Dynamics and Planetary Waves
Journal of the Atmospheric Sciences, 1994Abstract A simple model of the large-scale atmospheric circulation is studied. The model is based on the observation that the potential vorticity changes rapidly at the tropopause. This observation underlies the assumption that the potential vorticity on an isentropic surface, cutting through the tropopause, is piecewise uniform with a discontinuity at

Fluid Dynamics of Planetary Interiors
1990Following Monin (1973) and Gavrilin and Monin (1974), let us consider a simplified model of the Earth in three layers: (1) an outer solid spherical layer (mantle and crust) with an outer radius r1 ≈ 6370 km (radius of Earth) and an inner radius r2 ≈ 3470 km; (2) a liquid outer layer of the core; and (3) a solid spherical core with a radius r3 ≈ 1470 km,
