| Abstract: | The emergent polarization structure within spectral lines from rapidly rotating stars of spectral type B5V has been computed for the Mgii 4481 Å doublet and H for several angles of inclination and for rotational speeds of 0.5 and 0.9 of the critical rotational speed. It is found in this study that the emergent polarization within the Mgii 4481 Å doublet is currently unobservable with modern polarimeters. However, the polarization within H should be observable. |
