9. (a) Assume a star has constant temperature (T.) throughout with a density profile given by p(s) = re (+2) R where pe is a constant, r is the radial coordinate and R, is the outer radius of the star. Assuming that nuclear energy generation comes solely from the CNO cycle, derive an expression for the luminosity of the star (L.) in terms of the temperature (T.), stellar radius (R) and the constant for the nuclear energy generation rate (co). [You can assume that the mass fraction of Hydrogen is accounted for within the constant so in your derivation.) 161
