A Non-Lte Line-Blanketed Solar Model
Abstract
Line-blanketing effects are evaluated for selected strong solar lines and for representative cases from the remaining lines. A composite blanketing curve representing the effect of all lines is constructed from the combined blanketing curves for the selected and representative lines. Separate composite blanketing curves are obtained for four model atmospheres with different assumed temperature distributions, T1. The blanketing functions are used to compute blanketed model atmospheres, whose temperature distributions are Tb. A self-consistent model for which Tb T1 is obtained by iteration. In the self- consistent model the boundary temperature is 43300 K with estimated error limits of +1500. It is shown that the tendency for a temperature rise at small r produced by the Cayrel mechanism is strongly resisted by the blanketing mechanism and that temperatures as high as 46000 near m = I0- -t0- would require substantial input of mechanical energy.
