J/AJ/132/1539 Radial velocities of southern close binaries (Rucinski+, 2006) ================================================================================ Radial velocity studies of southern close binary stars. I. Winter systems. Rucinski S.M., Duerbeck H.W. =2006AJ....132.1539R ================================================================================ ADC_Keywords: Binaries, eclipsing ; Radial velocities Keywords: binaries: close - binaries: eclipsing - stars: variables: other Abstract: Radial velocity measurements and sine-curve fits to the orbital velocity variations are presented for nine contact binaries: V1464 Aql, V759 Cen, DE Oct, MW Pav, BQ Phe, EL Aqr, SX Crv, VZ Lib, and GR Vir. For the first five of these, our observations are the first available radial velocity data. For the three remaining radial velocity variables, CE Hyi is a known visual binary, while CL Cet and V1084 Sco are suspected to be multiple systems in which the contact binary is spectrally dominated by its companion (which itself is a binary in V1084 Sco). Five additional variable stars, V872 Ara, BD Cap, HIP 69300, BX Ind, and V388 Pav, are of unknown type, but most are pulsating stars; we give their mean radial velocities and vsini. Description: The observations were carried out with the ESO 1.52m telescope at ESO La Silla, equipped with a Boller & Chivens Cassegrain spectrograph. The observations were collected on four nights, 1998 August 8-11.
