Scientific paper

The Wolf-Rayet star AS 431 and five luminous blue stars in Cyg OB2 have been observed with the technique of speckle interferometry at the CFH 3.60 m telescope. The six objects turned out to be single in the angular separation range 40 marcsec -1.5 arcsec if the magnitude difference Δm at λ 7000 Å is less than 3 mag, and also in the range 20-40 marcsec if Δm ≃ 0. Implications are shortly discussed, mainly in the case of AS 431.
