Abstract
Based on high-resolution CCD spectra, radial velocity curves of HD64491 and HD141851 have been studied. Both stars are SB1 spectroscopic binaries with metal-weak characteristics. The PHOEBE code was used to derive the spectroscopic orbit solutions. The following parameters have been calculated for HD64491: Porb = 187.8 days, e = 0.5, a sin i = 0.39AU, q = m2/m1 &lid; 0.65. For the other star HD141851 we have obtained: Porb = 1073 days, e = 0.7, a sin i = 1.15AU, and q = m2/m1 &lid; 0.5.
