Various Orbital Solutions and Double Star Statistics.

摘要

For the past twenty years, the primary double star observational technique utilized at the US Naval Observatory (USNO) has been speckle interferometry. Our two speckle cameras have been used on a variety of telescopes: our 26-inch in Washington, the Naval Observatory Flagstaff Station (NOFS) 61-inch the McDonald Observatory 82-inch, the Mt. Wilson Observatory 100- inch and the twin 4 meter telescopes of Kitt Peak National Observatory (KPNO) and Cerro Tololo Interamerican Observatory (CTIO). While these instruments have each yielded many observations, they have been involved in rather different programs, with the 26-inch observing primarily the so-called 'neglected' pairs and larger instruments conducting duplicity surveys and observing close, astrophysically interesting systems.
