Brown J., Cassinelli J.P., Li Q., Kholtygin A., Ignace R. Optically Thick Clumps - Not the Solution to the Wolf-Rayet Wind Momentum Problem? ... 426 , 323-328 (2004) . The hot star wind momentum problem $\eta=\mdot \varv_{\infty}/(L/c) \gg 1$ is revisited, and it is shown that the conventional belief, that it can be solved by a combination of clumping of the wind and multiple scattering of photons, is not self-consistent for optically thick clumps. ...
