Vogt-Russell theorem




If the values of temperature, density, and chemical composition govern the pressure, opacity, and rate of energy generation in a star, then mass and chemical composition are sufficient to describe the structure of the star. The mass-radius relation and mass-luminosity relation follow from this theorem. Named after the German astronomer Heinrich Vogt (1890–1968) and Henry Russell.
