| Abstract: |
The reasons for the principle conclusion of a paper by Poe et al. (1989) are summarized. To the extent that a pure-absorption model is applicable, radiatively driven stellar winds have no well defined steady state. The non-Sobolev pure-absorption radiation force from Owocki et al., leads to the conclusion that the solution topology at the sonic point is a node, not a saddle or x as in the solar case. The number of transonic solutions increases from one unique solution for the x type to a range of solutions for the node-type topology. Thus, in the pure-absorption approximation, line driven winds can have a range of possible mass-loss rates and terminal velocities. |
