Preliminary Orbit of the Young Binary Haro 1-14c
Using the Keck Interferometer, we spatially resolved the orbit of thepre-main-sequence (PMS) binary, Haro 1-14c, for the first time. Wepresent these interferometric observations along with additionalspectroscopic radial velocity measurements of the components. Weperformed a simultaneous orbit fit to the interferometric visibilitiesand the radial velocities of Haro 1-14c. Based on a statistical analysisof the possible orbital solutions that fit the data, we determinedcomponent masses of M 1 = 0.96+0.27 0.08 M sun and M 2 = 0.33+0.09 0.02 M sun for the primary and secondary,respectively, and a distance to the system of 111+19 18 pc. The distance measurement is consistent with the closedistance estimates of the Ophiuchus molecular cloud. Comparing ourresults with evolutionary tracks suggests an age of 3-4 Myr for Haro1-14c. With additional interferometric measurements to improve theuncertainties in the masses and distance, we expect the low-masssecondary to provide important empirical data for calibrating thetheoretical evolutionary tracks for PMS stars.
