Description

A periodic (P=7sup(d).44+-0sup(d).10) photometric and spectroscopic variability of the star HD 191765 (WN6), connected with the ring-like nebula S109 is discovered. It is shown that this WR star is an eclipsing binary system with low-mass companion. The optical luminosity of this companion is > 1036 erg/s, which implies that the companion cannot be a normal star
