Résumé

Rocket-borne photon counters sensitive to bands ?? 1060–1180, ?? 1230–1350, and ?? 1350–1480 were used to measure the celestial ultraviolet radiation above the terrestrial atmosphere. The energy spectra of six objects, ? Leo, ? CMa, ? Ori, ?, ?, ? Ori (combined), ? Ori, and ? Tau were obtained. The comparison of them with those calculated with the stellar model atmospheres indicates the deficiency of about 1 mag. in the ultraviolet region, when corrected for interstellar extinction, for all stars except ? Tau. The observed spectrum of ? Tau agreed with the theoretical one for normal interstellar extinction. The effects of line blanketing were examined for B1 and B2 stars, and found to account for a part of the difference between the observed and the theoretical values.
