Mechanical Equilibrium: The Equilibrium between the Gravitational Force Per Unit Volume and the GraLet us consider a spherical star of radius ., in equilibrium, stratified in homogeneous concentric layers, whose center is .. We introduce an outward-directed axis . and a unit vector r on this axis, also outward-directed (see Figure 1).

The Determination of the Internal Structure by the Density Distribution ,(,),In the light of the relations established in the preceding chapter, it begins to be clear that the study of the internal structure of a star like the Sun consists in discovering how certain physical quantities like the density ., the temperature ., the total pressure ., etc., vary as functions of the distance . from the center.
