It is thereby shown that the internal energies of the C-O BIM solids and fluids both obey precisely the linear mixing formulas. We then present an accurate calculation of the phase diagram associated with freezing transitions in such BIM materials, resulting in a novel prediction of an azeotropic diagram. Discontinuities of the mass density across the azeotropic phase boundaries are evaluated numerically for application to a study of white-dwarf evolution., application/pdf}, pages = {309--315}, title = {Thermodynamic functions, freezing transition, and phase diagram of dense carbon-oxygen mixtures in white dwarfs}, volume = {40}, year = {1989}, yomi = {オガタ, シュウジ} }
