Panel a) ξ (Eq. (5)) as a function of wind velocity. Panel b) the relative contributions to ξ from fvel and . Curves in panels a and b have been calculated with κ0 = 5 and thermal speed 3t = 0.005 (in units of 3). Panels c) and d) analytic (Eq. (4), solid lines) and Monte-Carlo (dashed lines) based absorption part resonance line profiles from clumped winds, as compared to smooth results (dotted lines). Clumping starts at 3cl = 0.2 (rcl = 1.24). Panel c) Profiles for three different values of the line strength κ0 (indicated in the figure), with increased absorption for higher values of κ0. Only the κ0 = 1 profile is not saturated (i.e., does not display Ra = 0) for smooth models. Panel d) profiles for κ0 = 5 and different values of 3t, as indicated in the figure. No Monte-Carlo profile for the 3t = 0 case is shown (simply because we have not yet developed a “Sobolev version” of this code). Analytic and Monte-Carlo profiles display increased absorption for higher values of 3t, whereas all smooth profiles have Ra = 0.
