Effects that will bring the whole of the dust component of the nebula into the form of an extremely thin disk in the equatorial plane of the system are pointed out, and the final thickness of the dust-disk is investigated. Aspects of the gravitational development of the dust-disk are discussed together with the range of gravitational influence of a planet, the rate of mass increase of a planet, questions of the multiple formation of planets, the angular momentum of planets formed, the angular… 
Conservation laws and mass distribution in the planet formation process
Within the framework of the nebular theory of the origin of the solar system, conservation laws are applied to the condensation of a ring shaped cloud of orbiting particles. The final configuration
The formation of the outer planets
One of the outstanding problems in planetary cosmogony is to account for the depletion of hydrogen in the outer planets, Neptune and Uranus. It is suggested that these planets were originally similar
The formation of iron, stone, and mixed planetesimals in the early solar system
Abstract The interaction of dust grains with each other in a finite-temperature solar nebula are examined, taking into account the important fact that such grains would carry net steady-state charges
Numerical experiments on the stability of preplanetary disks
Abstract Gravitational stability of gaseous protostellar disks is relevant to theories of planetary formation. Stable gas disks favor formation of planetesimals by the accumulation of solid material;
A tidal hypothesis about the origin of planetary rotation
We assume that the solar tidal action on accreting protoplanets forced them to corotation. If this is true, and assuming a subsequent conservation of spin angular momentum, we can easily get a rough
Models of the formation of the solar nebula
Models of the collapse of a protostellar cloud and the formation of the solar nebula reveal that the size of the nebula produced will be the larger of RCF ≡ J2/k2GM3and RV ≡ (GMv/2cc3)12 (where J, M,
An interpretation of titius-bode law
The distance of a planet or a regular satellite from the central body is related to the mass of the planet or regular satellite. The boundary between two adjacent planetary regions (or regular
The early history of the earth—moon system
Abstract The study of the Earth—Moon system provides the connecting link between purely astronomical studies of the origin of the solar system and its planets, and geophysical and biological studies
Direct simulation of collision processes
The mass distribution of protoplanets is studied by a Monte Carlo technique. It is assumed that the bodies coalesce on collision and that their self-gravitation is important. It is found that over
Cosmogony of the solar system
This report is intended to cover research on solar system origin over the last 4 years. Emphasis has been placed on the physics of planetary accumulation mechanisms, although pertinent references on
