Radial velocities for the HD 27638B components

Listed in IVOA Registry (Virtual Observatory)

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.

Description

The secondary shows strong Li{lambda}6708 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.
