“…The second objection was based on Hayashi's theory that the sun went through a convective highly luminous phase early in its evolution (Hayashi, 1961;Hayashi et al, 1962; see also Cameron, 1963, 1965;Moss, 1968;Tayler, 1968). This would prevent water from condensing at distances of the order of 1 AU, as proposed by Hoyle to assist the growth of planetesimals.…”

Attempts to find a plausible naturalistic explanation of the origin of the solar system began about 350 years ago but have not yet been quantitatively successful. The period 1956-1985 includes the first phase of intensive space research; new results from lunar and planetary exploration might be expected to have played a major role in the development of ideas about lunar and planetary formation. While this is indeed the case for theories of the origin of the moon (selenogony), it was not true for the solar system in general, where ground-based observations (including meteorite studies) were frequently more decisive. During this period most theorists accepted a monistic scenario: the collapse of a gas-dust cloud to form the sun with surrounding disk, and condensation of that disk to form planets, were seen as part of a single process. Theorists differed on how to explain the distribution of angular momentum between sun and planets, on whether planets formed directly by condensation of gaseous protoplanets or by accretion of solid planetesimals, on whether the "solar nebula" was ever hot and turbulent enough to vaporize and completely mix its components, and on whether an external cause such as a supernova explosion "triggered" the initial collapse of the cloud. Only in selenogony was a tentative consensus reached on a single working hypothesis with quantitative results.

“…Main-sequence stars are in the evolutionary state occupied for most of their active, energy-generating lifetime converting hydrogen to helium through nuclear fusion reactions in the interior (Tayler 1968). Their radii range from 9 X lo9 cm to 1 X lo'* cm over the mass range 0.1-50 MO.…”

The present state of understanding of the cause of stellar explosions in novae and related systems is examined. Two physical phenomena unique to cataclysmic variables are the occurrence of a cool, Roche-lobe filling binary component with a compact companion, and a rotationally supported accretion disc about this compact companion. The conceptual advances that cataclysmic variables have contributed to our understanding of these astrophysical structures, largely through tests based on eruption behaviour in dwarf novae and symbiotic variables, are reviewed. The distinctly different conditions of classical nova explosions are briefly explored.

“…The logarithm of stellar luminosity is plotted against the logarithm of the effective temperature (increasing to the left). (Adapted from Tayler 1968. ) T h e T-Tauri stars as a class are irregularly variable, exhibiting large and small scale luminosity fluctuations.…”
