Scientific paper

A high-resolution long-wavelength IUE spectrum of the G0-G5Ia supergiant HR 8752 and its B main sequence companion is discussed. The supergiant, which dominates for wavelengths greater than approximately 2700 A, appears to have a normal spectrum. The spectrum of the B star contains several deep asymmetric absorption lines. It is argued that these lines are interstellar and not circumstellar in origin.
