On the Equations of Internal Constitution of Components in Close Binaries
Abstract
In the present paper, equations of the internal constitution of stable components in close binaries are deduced. The equation of equipotential surface was assumed of the form r=overline r(1+sum_i Y_i), where Y_i denotes the tesseral harmonics taken with respect to the centre of mass of a component. Their squares and higher powers were neglected as well as their changes within the period of revolution. The set of equations obtained is of the same form as for single stars. The independent variable is overline r - the mean distance of the equipotential surface from the centre of mass of the component. Dependent variables are: the pressure, temperature, flux of radiation and the mass of the portion of the star limited by a level surface.
