Adaptive Optics Photometry and Astrometry of Binary Stars. II. A Multiplicity Survey of B Stars We carried out a search for companions to B stars using the adaptiveoptics system of the Advanced Electro-Optical System 3.6 m telescope. Weobserved 70 B stars in the I band, finding 16 companions, 10 of whichare newly discovered companions. For each system with a detectedcompanion we give its measured astrometry and differential magnitude. Wethen put the observation in context of the system's known multiplicityand provide a somewhat crude estimate of its spectral type based on thesingle differential magnitude measurement. The separations range from0.2" to 7.31", and the differential magnitudes range from 1.41+/-0.01 to10.1+/-0.5. Finally, we present a list of the null detections anddiscuss the implications of null detections of selected stars.Based on observations made at the Maui Space Surveillance System,operated by Detachment 15 of the US Air Force Research Laboratory'sDirected Energy Directorate.
