dc.description.abstractRadial velocities of the primary component (B8V) of HU Tauri derived from the photographic spectra obtained during January 1974 to December 1974 and spectroscopic orbital elements from the analysis of the radial velocity curve of the B8V primary are given. The H {alpha}line of the late type secondary component is clearly detected on the photographic spectra taken around the quadratures and radial velocities of the secondary component are derived. The radial velocity semi amplitudes of the primary (K _1 ) and secondary (K _2 ) are found to be 60 km/sec and 234 km/sec respectively. The mass ratio M _2 /M _1 = K _1 /K _2 is found to be 0.2564. The detection of the H {alpha}line of the secondary is confirmed from the high resolution spectra that I obtained during 1981 and 1983 at quadratures using the 2.1-m McDonald observatory Otto Struve reflector telescope and high resolution coude Reticon spectrograph.en_US
