Icarus, 1968
Abstract The possibility of formating a planetary system, starting from a diffuse rotating cloud of gas and dust, as a result of accretion by a proto-Sun is investigated. It is found that a ring of relatively high density is formed in the equatorial plane of the proto-Sun gas cloud system.

Formation and Evolution of Planets
Astrophysics and Space Science, 1994The basic stages of the formation of the planets are considered. Decay of turbulence in the solar nebula allows the precipitation of dust particles to the solar nebula’s equatorial plane, their growth occurring by sticking at collisions and transformation into kilometer-sized bodies (planetesimals) partly by direct growth and partly via gravitational ...

Vistas in Astronomy, 1980
Abstract There are discussed briefly the following topics concerning the formation of the planets: 1.Formation of the protoplanetary nebula from a rotating interstellar magnetic cloud 2.The mass and temperature distribution in the protoplanetary nebula 3.The formation of planets by colliding planetesimals and by gas accretion 4.The distances, spin ...

Formation of the terrestrial planets
Earth, Moon, and Planets, 1994The early phases of formation in the inner solar system were dominated by collisions and short-range dynamical interactions among planetesimals. But the later phases, which account for most of the differences among planets, are unsure because the dynamics are more subtle. Jupiter’s influence became more important, leading to drastic clearing out of the

The origin of the Sun's planetary system is a long-standing problem but one whose solution may be in sight. Recent progress has been rapid and much has changed since the first edition of this book. This article will describe a reasonably coherent story for the formation of the planets, based on what people know today, with the obvious caveat that ...

This chapter presents the main characteristics of the formation scenario of the solar system. The fist sections summarize the observational constaints and the input of stellar physics, and reviewprevious formation models. The next section describes the currently accepted model, based on the collapse of a protoplanetary nebula into a disk and the ...

Formation of the Outer Planets
Space Science Reviews, 2005Models of the origins of gas giant planets and ‘ice’ giant planets are discussed and related to formation theories of both smaller objects (terrestrial planets) and larger bodies (stars). The most detailed models of planetary formation are based upon observations of our own Solar System, of young stars and their environments, and of extrasolar planets.
