Scientific paper

In the course of a large-scale multi-wavelength survey of bright B and Be stars we have discovered five hitherto unknown Be stars and one new Oe star: HR 1037 (B6Vn), 2806 (O9V), 5953 (B0.3IV), 6427 (B9.5V+A6III), 6747 (B0IIIn) and 8967 (B9V). We present Hα spectra and equivalent widths for these stars. We find that one known Be star, HR 6621 (B4IVe), probably has been misclassified as such because due to its binary nature its spectrum mimics Ho emission. From our results we infer - with 99% confidence - that the Be stars constitute at least 15% of all non-supergiant B stars in the Bright Star Catalogue.
