A Runaway Giant in the Galactic Halo
Philip Massey, Stephen E. Levine, Kathryn F. Neugent +3
New evidence provided by the Gaia satellite places the location of the runaway star J01020100-7122208 in the halo of the Milky Way (MW) rather than in the Small Magellanic Cloud as…
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…
Distances of Dwarf Carbon Stars
Hugh C. Harris, Conard C. Dahn, John P. Subasavage +8
Parallaxes are presented for a sample of 20 nearby dwarf carbon stars. The inferred luminosities cover almost two orders of magnitude. Their absolute magnitudes and tangential velo…
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…
APASS Landolt-Sloan BVgri photometry of RAVE stars. I. Data, effective temperatures and reddenings
U. Munari, A. Henden, A. Frigo +24
We provide APASS photometry in the Landolt BV and Sloan g'r'i' bands for all the 425,743 stars included in the latest 4th RAVE Data Release. The internal accuracy of the APASS phot…
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…
