Abstract: Spatially resolving the orbits of double-lined spectroscopic binaries provides a way to measure the dynamical masses of the component stars. At the distances to the nearest star-forming regions, high angular resolution techniques are required to resolve these short-period systems. In this paper, I provide an overview of the few low-mass pre-main-sequence spectroscopic binaries that have been resolved thus far using long-baseline optical/infrared interferometers. I also compiled a list of known spectroscopic binaries in nearby star-forming regions (Taurus, Orion, Ophiuchus, Scorpius-Centaurus, etc.) and show that with modest improvements in the sensitivity of interferometers with 200–300 meter baselines, we can build a significant set of pre-main-sequence stars with precise mass determinations. This is important for validating and distinguishing among the theoretical calculations of evolution for young stars.
