Scientific paper

We propose to observe middle and late-type giant and supergiant stars whose TD-1 and ANS fluxes indicate the presence of a hot component. Some of the secondaries are seen weakly in optical spectra but cannot be classified accurately, while others are UV discoveries. The companions apparently lie on the main sequence, and thus can be used to derive more accurate luminosities than can now be done for individual giants and supergiants. Since the companions contribute little light in the optical region, ultimately this group can be useful in calibrating the upper end of the Wilson-Bappu relations. Evidence for enhanced mass loss for the secondaries or warm plasma around the stars, as seen in some systems of this kind, will be examined.
