Spectra of the He iλ447.1 nm (left) and Hϵ (right) lines, obtained with X-Shooter (black line) and Narval (gray line). FASTWIND model profiles are overplotted for B6 and B7 giants and main-sequence stars. The inset in the right panel shows a detail of the line wing. The B7 III model provides the best fit with the observed profiles. The Ca ii H λ393 nm and Mg iiλ448 nm lines are also visible.
