Isolating the effects of chemical composition in the equation of state
Abstract
The effects of different chemical compositions and of different equation-of-state formalisms on a solar structure are often mixed. The reason being that the chemical composition in modern, sophisticated equations of state cannot be easily adjusted. Therefore, most of related studies simply consider the combined effect of the two, rather than individual effect. The actual error in the formalism of the equation of state is thus inevitably obscured.
The aim of this paper is to examine and isolate the effects of varying chemical compositions, in hope to help to extract the effects purely from the formalism of equation of state. We present a strategy and the results of examining the effects of the ionization of individual element.- Publication:
