| Abstract: | Flux-constant model has been constructed for solar atmosphere, including OH-bound-free opacity, but without any line opacity, atomic, ionic or molecular. A comparison between the theoretical and observed intensity and flux shows that OH-opacity can account for the missing solar opacity, except at those wavelengths where the intensity shows the presence of numerous absorption lines, provided the unknown oscillator strength of the transition is 0.3. The T –  relation, however gives larger temperatures at smaller depths than those by the empirical model. This and the large theoretical flux in the spectral region with heavy line absorption indicate the importance of line opacity.On leave from Tata Institute of Fundamental Research, Bombay-400005, India. |
