The influence of inhomogeneities on hot star wind model predictions

We study the effect of wind inhomogeneities (clumping) on O star wind model predictions. For this purpose we artificially include clumping into our stationary NLTE wind models. As a result of the inclusion of optically thin clumps the radiative line force is increased compared to corresponding unclumped models,with a similar effect on either the mass-loss rate or the terminal velocity. When the clumps are allowed to be optically thick in continuum,on the other hand,the radiative force and consequently the mass-loss rate decreases alternatively.
