Adaptive optics photometry and astrometry of binary stars. II. A multiplicity survey of B stars.


Abstract (from CDS):

We carried out a search for companions to B stars using the adaptive optics system of the Advanced Electro-Optical System 3.6 m telescope. We observed 70 B stars in the I band, finding 16 companions, 10 of which are newly discovered companions. For each system with a detected companion we give its measured astrometry and differential magnitude. We then put the observation in context of the system's known multiplicity and provide a somewhat crude estimate of its spectral type based on the single differential magnitude measurement. The separations range from 0.2" to 7.31", and the differential magnitudes range from 1.41±0.01 to 10.1±0.5. Finally, we present a list of the null detections and discuss the implications of null detections of selected stars.
