Abstract: The effects of rapid rotation and bi–stability upon the density contrast between the equatorial and polar directions of a B[e] supergiant are investigated. Based on a new slow solution for different high rotational radiation–driven winds and the fact that bi–stability allows a change in the line–force parameters (α, k, and δ), the equatorial densities are about 102–103 times higher than the polar ones. These values are in qualitative agreement with the observations. This calculation also permits to obtain the aperture angle of the disk.
