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 years. 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 half maxima of the images are presented.

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 adaptive optics system of the Advanced ElectroOptical 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 00 to 7.31 00 , and the differential magnitudes range from 1:41 AE 0:01 to 10:1 AE 0:5. Finally, we present a list of the null detections and discuss the implications of null detections of selected stars.

“…During the observations the seeing ranged ranged from 1.2-2.0 ′′ , as reported by the Day Night Seeing Monitor at the observatory (Bradley et al 2006). This is worse than average, and in combination with the relatively dim object for the AO system, produced data with below average image quality.…”

In August 2002, the near-Earth asteroid 2002 NY 40 , made its closest approach to the Earth. This provided an opportunity to study a near-Earth asteroid with a variety of instruments. Several of the telescopes at the Maui Space Surveillance System were trained at the asteroid and collected adaptive optics images, photometry and spectroscopy. Analysis of the imagery reveals the asteroid is triangular shaped with significant self-shadowing.The photometry reveals a 20-hour period and the spectroscopy shows that the asteroid is a Q-type.
