USNO Bright Star Catalog (UBSC) is a new astrometric catalog of 1423 brightest stars covering the entire sky, which is published online. It is nearly complete to mag except f…
Looking for astrometric signals below 20 m/s: A Jupiter-mass planet signature in Eri
Valeri V. Makarov, Norbert Zacharias, Charles T. Finch
The USNO ground-based astrometric program URAT-Bright in combination with the Hipparcos mission epoch astrometry provides precise proper motions of a thousand bright stars in the s…
Looking for astrometric signals below 20 m/s: A candidate exo-Jupiter in Pav
Valeri V. Makarov, Norbert Zacharias, Charles T. Finch
We use a combination of Hipparcos space mission data with the USNO dedicated ground-based astrometric program URAT-Bright designed to complement and verify Gaia results for the bri…
The Solar Neighborhood XLIV: RECONS Discoveries within 10 Parsecs
Todd J. Henry, Wei-Chun Jao, Jennifer G. Winters +7
We describe the 44 systems discovered to be within 10 parsecs of the Sun by the RECONS team, primarily via the long-term astrometry program at CTIO that began in 1999. The systems…
URAT South Parallax Results: Discovery of New Nearby Stars
Charlie Finch, Norbert Zacharias, Wei-Chun Jao
We present 916 trigonometric parallaxes and proper motions of newly discovered nearby stars from the United States Naval Observatory (USNO) Robotic Astrometric Telescope (URAT). Ob…
Speckle Interferometry at the U.S. Naval Observatory. XXII
Brian D. Mason, William I. Hartkopf
The results of 4,747 intensified CCD observations of double stars, made with the 26-inch refractor of the U.S. Naval Observatory, are presented. Each observation of a system repres…
