Aims. We undertake an optical and ultraviolet spectroscopic analysis of a sample of 20 Galactic B0-B5 supergiants of luminosity classes Ia, Ib, Iab, and II. Fundamental stellar parameters are obtained from optical diagnostics and a critical comparison of the model predictions to observed UV spectral features is made. Methods. Fundamental parameters (e.g., ${T_{\rm eff}}$, ${\rm log L_{*}}$, mass-loss rates and CNO abundances) are derived for individual stars using CMFGEN, a nLTE, line-blanketed… Expand
