Title:  Precise Masses of Low-Mass Eclipsing Binaries

We present new and updated mass measurements for a sample of low-mass eclipsing binaries using Keck archival data and new observations taken on the 2.7 m telescope at McDonald Observatory. We explore multiple methods for precisely measuring radial velocities, including multidimensional correlation functions as well as rotational broadening functions. Precise mass determinations for these stars are the first phase of a project to study low-mass eclipsing binaries with IGRINS. By adding additional stellar parameters to the mass-radius relation (e.g. metallicity, rotation), we aim to resolve the discrepancy that exists between observations and models of low mass stars.
