Abstract

Radial-velocity measurements and sine-curve fits to the orbital velocity variations are presented for 14 close binary stars, S Ant, TT Cet, TW Cet, AA Cet, RW Dor, UX Eri, YY Eri, BV Eri, CT Eri, SZ Hor, AD Phe, TY Pup, HI Pup and TZ Pyx. All are double-lined binaries and all except the last one are contact binaries. The orbital data must be considered preliminary because of the relatively small number of observations (6 - 12), a circumstance which is partly compensated by the good definition of the broadening functions used for the RV determinations.
