The Double-Lined Spectroscopic Binary Haro 1-14c

Abstract

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 $0.310\pm 0.014$. With an estimated photometric primary mass of 1.2 $M_{\odot }$, the secondary mass is $\sim 0.4M_{\odot }$ and the projected semi-major axis is $\sim 1.5$ 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.
