New Neighbors: Parallaxes of 18 Nearby Stars Selected from the Lspm-north Catalog1
We present astrometric parallaxes for 18 suspected nearby stars selected from the LSPM-north proper motion catalog. Sixteen objects are confirmed to be main sequence M dwarfs within 16 parsecs of the Sun, including three stars (LSPM J0011+5908, LSPM J0330+5413, LSPM J0510+2714) which lie just within the 10 parsec horizon. Two other targets (LSPM J1817+1328, LSPM J2325+1403) are confirmed to be ...
متن کاملKinematic Structure in the Galactic Halo at the North Galactic Pole: RR Lyrae and BHB Stars show different kinematics
Radial velocities and proper motions (derived from the GSC-II database) are given for 38 RR Lyrae (RRL) stars and 79 blue horizontal branch (BHB) stars in a ∼ 200 deg area around the North Galactic Pole (NGP). Both heliocentric (UVW) and galactocentric (VR, Vφ, Vz) space motions are derived for these stars using a homogeneous distance scale consistent with (m−M)0=18.52 for the LMC. An analysis ...
متن کاملOn the Hipparcos parallaxes of O stars
We compare the absolute visual magnitude of the majority of bright O stars in the sky as predicted from their spectral type with the absolute magnitude calculated from their apparent magnitude and the Hipparcos parallax. We find that many stars appear to be much fainter than expected, up to five magnitudes. We find no evidence for a correlation between magnitude differences and the stellar rota...
متن کاملInfrared monitoring of OH/IR stars near the Galactic Center
We have monitored 102 fields of size 1′ × 1′ within ∼0.7◦ of the Galactic Center for 1200 days in the K band. Each field was centered on one of the OH/IR stars found by Lindqvist et al. (1992). Infrared colours J−K, H−K and K−L were also obtained. Periods have been determined for 80 known OH/IR stars, including 5 from Sjouwerman (1997), and a further 29 previously unknown long-period variables ...
متن کاملHubble Space Telescope Fine Guidance Sensor Parallaxes of Galactic Cepheid Variable Stars: Period-luminosity Relations
We present new absolute trigonometric parallaxes and relative proper motions for nine Galactic Cepheid variable stars: l Car, ζ Gem, β Dor, W Sgr, X Sgr, Y Sgr, FF Aql, T Vul, and RT Aur. We obtain these results with astrometric data from Fine Guidance Sensor 1r, a white-light interferometer on Hubble Space Telescope. We find absolute parallaxes in milliseconds of arc: l Car, 2.01± 0.20 ; ζ Gem...
