Scientific paper

From spectrophotometric measurements of hydrogen line intensities, uvby photometry and photoelectrically determined H-beta and H-gamma indices of 75 B2-B6 main-sequence stars, effective temperature and surface gravity are derived by using the model atmospheres computed by Kurucz (1974). Comparisons between the g values and the MK luminosity classification show good agreement for the MK standard stars but rather serious disagreement for the average stars in such a way that most of the stars classified in luminosity class V really belong to class IV. Using the evolutionary model sequences calculated by Hejlesen et al. (1972) the stellar mass, age and luminosity are determined from the uvby and beta data through effective temperature and surface gravity. The theoretically derived luminosities are in excellent agreement with the luminosities derived by calibrations.
