Fig. 6


Observed and synthetic line profiles for λ Cep. Dotted lines are the observations. Solid line profiles are calculated from the inhomogeneous radiation-hydrodynamic model of λ Cep (Table 1), and dashed lines from a corresponding fastwind model including microclumping. The long-dashed line in the upper left panel is from a RH model in which the density has been scaled to mimic an increase in the mass-loss rate by 50%.
