1905 20160701171655.0 ASTROimport-62 Blomme, R. 1991 Models for the radiatively driven stellar wind of early-type stars The radiatively driven wind theory does not correctly predict the observed values of the terminal velocity and the mass loss rate of early-type stars. This paper investigates the influence of some of the assumptions on these discrepancies. Consideration is given to rotation, limb-darkening, errors in the oscillator strengths, and changes in the abundances. Although no single effect can explain the discrepancy in the terminal velocity, a combination of effects probably can. However, the factor of two by which the theory underestimates the mass loss rates. But taking into account the uncertainty on the observed values, it is perhaps possible that the theoretical predictions are still reasonably correct. This would have important consequences for the evolution of massive stars. Astronomy and Astrophysics 246 1991 199-209 http://esoads.eso.org/abs/1991A%26A...246..199B published in REFERD
