Parallaxes, Proper Motions, and Near-Infrared Photometry for 173 L and T Dwarfs From The US Naval Observatory Infrared Astrometry Program
Frederick J. Vrba, Adam C. Schneider, Jeffrey A. Munn +11
We present near-infrared parallax and proper motion astrometry for 74 L-dwarfs and 99 T-dwarfs, as single objects or in binary systems, obtained with the ASTROCAM astrometric image…
Distant White Dwarfs in the US Naval Observatory Flagstaff Station Parallax Sample
S. K. Leggett, P. Bergeron, John P. Subasavage +18
This paper presents new trigonometric parallaxes and proper motions for 214 stars. The measurements were made at the US Naval Observatory Flagstaff Station (NOFS) between 1989 and…
CCD Parallaxes for 309 Late-type Dwarfs and Subdwarfs
Conard C. Dahn, Hugh C. Harris, John P. Subasavage +16
New, updated, and/or revised CCD parallaxes determined with the Strand Astrometric Reflector at the Naval Observatory Flagstaff Station (NOFS) are presented. Included are results f…
The Binary White Dwarf LHS 3236
Hugh Harris, Conard Dahn, Trent Dupuy +13
The white dwarf LHS 3236 (WD1639+153) is shown to be a double-degenerate binary, with each component having a high mass. Astrometry at the U.S. Naval Observatory gives a parallax a…
Infrared Excess in the Be Star Delta Scorpii
R. J. Halonen, C. E. Jones, T. A. A. Sigut +6
We present infrared photometric observations of the Be binary system delta Scorpii obtained in 2006. The J,H and K magnitudes are the same within the errors compared to observation…
Parallax and Luminosity Measurements of an L Subdwarf
Adam J. Burgasser, Frederick J. Vrba, Sébastien Lépine +5
We present the first parallax and luminosity measurements for an L subdwarf, the sdL7 2MASS J05325346+8246465. Observations conducted over three years by the USNO infrared astromet…
