Source Function in a Non-Equilibrium Atmosphere. III. The Influence of a Chromosphere.
We apply the methods developed in the preceding two papers to investigate the depth dependence of the source function for resonance lines in an atmosphere having a chromospheric distribution of T, superposed upon a photospheric one. The derived behavior of SL( ) for the neutral and ionized metals differs and mimics the observed behavior of such lines. The hydrogen Balmer lines should behave like the neutral metals, and the predicted behavior agrees with our earlier empirical results.
