By using elementary astrophysical concepts, we show that for any self-luminous astrophysical object the ratio of radiation energy density inside the body (ρr) and the baryonic energy density (ρ0) may be crudely approximated, in the Newtonian limit, as ρr/ρ0∝GM/Rc2, where G is constant of gravitation, c is the speed of light, M is gravitational mass and R is the radius of the body. The key idea is that radiation quanta must move out in a diffusive manner rather than stream freely inside the body… CONTINUE READING
