Models of Dense Stars
Abstract
The aim of this paper is to present the results of a construction of five models of composite stellar configurations, consisting of an energygenerating convective core surrounded by sourcefree envelope in radiative equilibrium, and of sufficient density for the coefficient of absorption to vary approximately as inverse square of the local temperature. The principal characteristic of such models proved to be their very high degree of central condensation; their central densities being 10^{3} 10^{4} times as large as the mean density of the composite configuration. The relevance of such models to the internal structure of subdwarf components of close binary systems with periods less than a day is briefly pointed out.
