Studies of eclipsing binary stars are key to accurate, empirical measurements of the masses, radii, and temperatures of stars, which are necessary for understanding stellar evolution and for deriving well- calibrated theoretical models. However, only six pre-main-sequence eclipsing binaries with masses below 1 solar mass have so far been published. We have discovered TYC 7310-503-1 to be a low-mass, pre-main- sequence eclipsing binary in the Upper-Centaurus-Lupus star-forming region with component star masses of ~ 0.8 and ~ 0.5 M_&sun;; this is one of the lowest mass young stellar eclipsing binaries yet found, and the first that is associated with a star-forming region other than Orion. Here we propose precise time-series photometry and spectroscopy of TYC 7310-503-1 which will permit the determination of accurate stellar masses and radii for this very young, very low-mass benchmark system.
