The Formation Of Planetary Systems
1997The orbital characteristics of the planets imply their formation in the rotating disk of gas and dust that earlier produced the sun. Observations of star-forming regions suggest that such protoplanetary disks are common around young stars, and hence that planetary systems are abundant in the galaxy.

Possible models of the planetary systems formations
International Journal of Modern Physics A, 2020We discuss extended model of planetary system formation. Gravitational collapse of protoplanets leads to the formation of planets and their satellite systems. We consider the hypothesis of a two-stage mechanism of formation of satellite system. Small satellites are formed from the remnants of a collapsing protoplanetary cloud, and large satellites are

The Formation of the Planetary System
2014This paper presents, in rather popular form, a theory of planet formation in the tradition, founded by I. Kant and P.S. Laplace, stating that planets originate from dust around the sun. The paper uses the most recent advances of the theory of turbulence.

Formation of Planetary Systems
2019The planet formation process regulates the planetary surface environment during the early phase when life may emerge. The frequency and diversity of “habitable planets” are predicted by the planet formation model. Here we review our current understanding of planet formation for our Solar system and general exoplanetary systems. The discovery of diverse

Formation of planetary and satellite systems
Astrophysics and Space Science, 1978A solar nebula-type theory recently published by the author can explain much more about our planetary system and the satellite systems than all other theories known to date. Here only a few additional and relatively simple aspects are pointed out, especially the formation of the Moon and of the Martian satellites.

Radiation forces and the formation of planetary systems
Astrophysics and Space Science, 1990We briefly support on some new results about the influence of the rotation and finite size of a stellar radiation source on dust particle orbits, emphasizing the possibility of stable orbits, in the equatorial plane, for dust sizes near the radiation pressure limit.

Formation of Stars and Planetary Systems
1998The number of stars in the Milky Way may be as high as a hundred billion. Yet we have only the most incomplete notions of how all these stars formed. Within the past decade, we have also become aware of the many planetary systems orbiting all these stars. Yet we are only just beginning to understand how our own system of planets condensed.

Magnetic Fields and Planetary Systems Formation
2014The magnetic field of a protostellar disk is a field that permeates the rotating disk of gas and dust about a protostar fromwhich planets may form. Magnetic field lines rotate with the ionized component of the disk material and are subject to an instability that is the likely source of turbulence and viscous drag within a disk.

Meteorites and Planet Formation
Reviews in Mineralogy & GeochemistryMeteorites are a remarkable resource. They capture the imagination of people worldwide with their spectacular entry through Earth's atmosphere as fireballs, and their exotic character of being pieces of other worlds.
