Astrometric and photometric measurements of binary stars with adaptive optics: observations from 2002.

ROBERTS L.C.Jr

Abstract (from CDS):

The adaptive optics system at the 3.6-m AEOS telescope was used to measure the astrometry and differential magnitude in I band of 56 binary stars in 2002. The astrometric measurements will be of use for future orbital determination, and the photometric measurements will be of use in estimating the spectral types of the component stars. Two candidate companions were detected, but neither is likely to be gravitationally bound. Nine systems had not been observed in over 40 yr. Eight of these are shown to share common proper motion, while HD 182352 is shown to be a background star. One of the two components of the HD 114378 (α Com) is shown to be a variable star of unknown type. In addition, 86 stars were unresolved and the full width at half-maximum of the images are presented.
