J/AZh/75/197        Energy distribution of O5-O8 stars    (Knyazeva+, 1998)

On the normal spectral energy distribution in stellar spectra: O5-O8 stars. Knyazeva L.N., Kharitonov A.V. <Astron. Zh. 75, 197 (1998)> =1998AZh....75..197K =1998ARep...42..169K
ADC_Keywords: Stars, OB ; Energy distributions ; Spectrophotometry Description: The normal spectral energy distribution for spectral subtypes from O4 to O8 for luminosity classes V,IV and III are derived. Three photometrically uniform catalogs served as the source of the spectrophotometric data used. Synthetic color indices for all spectral types are calculated using the energy distribution curves obtained. File Summary:
