Beginning of ReadMe : J/AJ/131/1702 Radial velocities for the HD 27638B components (Torres+, 2006) ================================================================================ The multiple system HD 27638. Torres G. <Astron. J., 131, 1702-1711 (2006)> =2006AJ....131.1702T ================================================================================ ADC_Keywords: Stars, double and multiple ; Binaries, spectroscopic ; Radial velocities Keywords: binaries: spectroscopic - binaries: visual - stars: individual (HD 27638) - stars: late-type - techniques: radial velocities - techniques: spectroscopic Abstract: We report spectroscopic observations of HD 27638B, the secondary in a visual binary in which the physically associated primary (separation  19") is a B9 V star. The secondary shows strong Lilambda6708 absorption, suggesting youth, and has attracted attention in the past as a candidate post-T Tauri star, although this has subsequently been ruled out. It was previously known to be a double-lined spectroscopic binary (F8+G6) with a period of 17.6days and to show velocity residuals indicating a more distant massive third companion with a period of at least 8yr. Description: Spectroscopic observations of HD 27638B were conducted at the Center for Astrophysics (CfA) between 1988 September and 2004 December (with a 6yr gap from 1990 March to 1996 November), mostly with an echelle spectrograph on the 1.5m Wyeth reflector at the Oak Ridge Observatory (Harvard, Massachusetts). Occasional observations were also made with nearly identical instruments on the 1.5m Tillinghast reflector at the F. L. Whipple Observatory (Mount Hopkins, Arizona) and the MMT Observatory (also on Mount Hopkins, Arizona).
