Static stellar models with helium cores.
Abstract
The properties of static stellar models with helium cores are discussed with particular emphasis on those features which produce multiple solutions. A stellar model is obtained by fitting core solutions to envelope solutions in a U-V plane. The large number of possible solutions which have been found in earlier numerical computations (up to nine different solutions for a model of given mass and chemical composition) can be explained by the various intersections of the envelope and the core fit-curves, and the typical features of the fit-curves can in turn be identified with the corresponding physical effects
