Table 7

Summary of the wavelength dependencies of the flux derived for simplified models for the chromosphere and the ionised wind.

Optically thin Optically thick

chromosphere λ4Fλ ∝ λ2.1 λ4Fλ ∝ λ0
ionised wind λ4Fλ ∝ λ2.1 λ4Fλ ∝ λ1.4

Notes. The table gives the wavelength dependence for an optically thick ionised wind with a density distribution ne ∝ rβ with β = 2. For β = 1.5 we have λ4Fλ ∝ λ2.1 and for β → ∞ we have λ4Fλ ∝ λ0.
