The effects of electron scattering and wind clumping for early emission line stars

Using two independent codes, a detailed study of the influence of electron scattering on line profiles arising from stellar winds around early emission line stars have been made. These calculations indicate that the assumption of isotropic scattering gives acceptable answers when compared with more accurate calculations using a dipole phase function. On the other hand the use of angle-averaged redistribution functions can noticeably affect the strength of the predict electron scattering wings. In addition it is shown that the velocity adopted for the Doppler line absorption profile can dramatically influence the strength of electron scattering wings for a line that is optically thick throughout most of its formation region
