Unformatted text preview: Problem 8: Stellar emission The conditions in stellar photospheres are often well represented by Local Thermodynamic Equilibrium (LTE). Neglecting scattering please derive a quantitative estimate for the angular distribution of the intensity, I , that would be seen by an outside observer. a) Assume the temperature T is constant, independent of the vertical optical depth, which itself is assumed independent of frequency. b) Assume the temperature is constant in each of three zones with values T ( z ) = T z 1 2 T 1 z 2 4 T 2 z...
