"The spectrum of the Be star HD 161306 is shown to vary periodically with a period close to 100 days. The radial velocity of the He I 6678 A emission peak varying in antiphase to the radial velocity of the Halpha emission wings component suggests that the star is a binary similar to phi Per, 59 Cyg, or FY CMa, i.e. a radiatively interacting Be binary - a rare case among Be stars. This type of object is also called a phi Per-type binary or Be + sdO binaries. The range of radial-velocity variations of the strong emission peak in the helium line observed in HD 161306 is about 180 km/s, similar to what is observed for these systems. We therefore conclude that HD 161306 may represent another case of a Be star with a hot subdwarf companion." . "Kotkov\u00E1, Lenka" . "HD 161306: a radiatively interacting Be binary?" .
