Description

The binary nature of the central star in the Red Rectangle HD 44179 has been confirmed using the Imperial College speckle interferometer on the AAT. The position angle of 146 +- 30 and separation 0.29 +- 0.02 arcsec are given for 1981 November 11. An orbital period of 60 +- 5 yr and a total mass of the two components of the binary approx.= to 31 sun masses are both predicted. No correlation between the inclination of the orbit and the striking geometry of the nebulosity is found. (author)
