Radial Velocity Studies of Southern Close Binary Stars. II. Spring/Summer Systems

Radial-velocity measurements and sine-curve fits to the orbital velocityvariations are presented for 14 close binary stars, S Ant, TT Cet, TW Cet, AACet, RW Dor, UX Eri, YY Eri, BV Eri, CT Eri, SZ Hor, AD Phe, TY Pup, HI Pup andTZ Pyx. All are double-lined binaries and all except the last one are contactbinaries. The orbital data must be considered preliminary because of therelatively small number of observations (6 - 12), a circumstance which ispartly compensated by the good definition of the broadening functions used forthe RV determinations.Comment: accepted by AJ for Januray 2007; order of the authors changed re V.
