Scientific paper

The first spectroscopic orbital solutions for the double-line binaries HD 104451 and HD 141458 are presented. The instrumental configuration for the observations is described, and the absorption lines measured in the spectra are shown. The measured radial velocity, mean error, and number of lines measured for each component are presented for both binaries. Orbital elements and velocity curves obtained for both binaries are also presented. HD 141458 has a moderately large orbital eccentricity, but otherwise neither system is exceptional in any way.
