The Theory of Hot White Dwarfs Based on a Two-Component Equation of State

A variant of the theory of hot white dwarfs of small and intermediate masses is proposed using a model with a partially degenerate ideal relativistic electron gas and an ideal classical nuclear gas.  By modeling the radial temperature distribution, a reduced three-parameter equation of state was obtained as a function of matter density.  Based on numerically obtained solutions of the equilibrium equation, the characteristics of white dwarfs were determined as functions of the model parameters.  The inverse problem was solved – the values of the model parameters were cal

Thermodynamic and hydrogeological conditions of forming the hydrocarbon deposits of the Pre-Black Sea aquiferous basin

Purpose. Finding the connection between the thermodynamic conditions of hydrocarbon mixtures synthesis and zones of oil and gas accumulation. Methodology. The thermodynamic eguilibrium depths of gas and gas-condensate deposits were fixed by the method of eguilibrium constants of independent reactions based on the chemical composition of hydrocarbons re-counted on chemical elements. The investigations of formation waters, natural gases and water-dissolved gases were based on the methods of chemical, elementary spectral, atomic absorption and gas chromatographic analysis. Results.
