Scientific paper

Spectroscopic orbits are determined for the 4-day, F8 V eclipsing binary UX Mensae. The masses of the binary components are 1.24 and 1.20 solar masses with errors of + or - 0.5 percent. The results of the analysis of the uvby light curves by Clausen and Gronbech (1976) are confirmed. The metal abundance is found to be Fe/H = +0.04 + or - 0.10. Absolute dimensions are computed for the binary. Theoretical evolutionary sequences for the masses and metal abundance are interpolated from the models of VandenBerg (1988) and Andersen et al. (1988).
