摘要：
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-circle dot, the secondary mass is similar to0.4 M-circle dot and the projected semimajor axis is similar to1.5 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.
