The Capture Theory and Planetary Condensation

Abstract
The condensation of planets under the conditions of Woolfson's capture theory of the origin of the solar system is described. It is shown that material captured by the Sun, during an encounter with another star, would probably not recondense to form planets under the conditions originally specified. Different star encounters are studied using numerical analysis, and it is shown that as a result of a ‘fast ’ encounter, the Sun could capture material which would recondense to form planets and take up orbits which are comparable to those observed in the solar system. The probability of such star encounters, and also the origin of planetary satellites, are briefly discussed.
