Rotation and the wind momentum-luminosity relation for extragalactic distances

The effects of axial stellar rotation on the wind-momentum relation (WLR) f or determining the extragalactic distances are investigated. Despite the fa ct that the mass loss rates grow quite a lot with rotation, remarkably the effects on the WLR are found to be very small on average. As an example, fo r an average orientation angle between the rotation axis and the line of si ght, the luminosity would be overestimated by 5.9% for a star rotating at 9 0% of its break-up rotational velocity. Different orientation angles betwee n the rotation axis and the line of sight produce some limited scatter.
