We request KPNO 4m time to obtain red spectra of several low-mass eclipsing binaries. Good signal to noise spectra (20-30) at high dispersion (0.5Aper pixel) are needed to get velocities at the 5- 8km/s precision. Velocities will be coupled with contemporaneous photometry so that light and velocity curves can be used to determine the masses, radii, and luminosities using a binary star program (Wilson- Devinney) as well as modeling dark spots due to magnetic activity. One of the primary targets will be LP133-373 and its tertiary white dwarf LP133-374, which will have its atmosphere modeled yielding an accurate mass and temperature so that the systems age can be determined as well. The binaries' refined masses and radii will enable comparisons to current models (M-R relations) of these poorly sampled stars.
