Approximation of the flux-averaged extinction coefficient κH in models for a dust shell with a powerlaw wavelength variation of the extinction coefficient for different mass-loss rates (in units M⊙ a-1). Solid line: Result of a complete model calculation of radiative transfer. Dashed line: approximation according to Eq. (19).
