Scientific paper

We report detection of the low-mass secondary in the spectroscopic binary Haro 1-14c in the Ophiuchus star forming region. The secondary/primary mass ratio is 0.310± 0.014. With an estimated photometric primary mass of 1.2 M&sun;, the secondary mass is ˜ 0.4 M&sun; and the projected semi-major axis is ˜ 1.5 AU. The system is well-suited for astrometric mapping of its orbit with the current generation of ground-based IR interferometers. This could yield precision values of the system's component masses and distance.
