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.

Note (1): The weights were used in the orbital solutions and can take
values of 1.0, 0.5 or 0; the zero weight observations may be
eventually used in more extensive modeling of broadening functions.
