Speckle Interferometry at the USNO Flagstaff Station: Observations Obtained in 2008 and Nine New Orbits.

摘要

Results are presented for 299 speckle interferometric observations of double stars, obtained in 2008 at the USNO Flagstaff Station using the 1.55 m Kaj Strand Astrometric Reflector. Separations range from 0. 15 to 9. 88, with a median of 2. 22. This observing run concentrated on neglected systems, as well as systems in need of improved orbital elements; new orbital solutions have been determined for nine systems as a result.
