Abstract

Our de-reddened fluxes, together with the ultraviolet measurements of Thompson et al. (1978), have been compared with those of Kurucz’s (1979) model atmospheres to derive effective temperatures of some O emission, Be and Ae stars. With the measured monochromatic fluxes we determined their angular diameters and luminosities. It is found that the majority of the stars are cooler than the Zero-Age Main Sequence (ZAMS), suggesting that they are slightly more evolved than ZAMS stars.

The observations were made at the Observatoire de Haute Provence (France) and La Silla (E.S.O., Chile).
