The interior of a star consists of the convection region and radiation. The energy transfer process in the convection region and radiation is different which indicates the energy transfer process in the star. The energy transfer is affected by the density of the star. The radiation energy transfer equation with non-homogeneous density has been formulated. The density of a non-homogeneous star is the density that only depends on the distance. It has been obtained the formulation of an energy transfer equation in radiation with a non-homogeneous density in the form of a star temperature gradient. This equation is obtained by formulating the relationship between the specific intensity of the beam, the flux, and the luminosity of the star. The density of a non-homogeneous star affects the luminosity and flux of the star. Meanwhile, the star temperature gradient equation does not depend on the density of non-homogeneous stars.
