Binaries: Spectroscopic, Radial Velocities

Scientific paper

The triple system is spectroscopically unresolved, but the Doppler information available in the composite spectrum can be used to recover the contributions of the individual components. Therefore, extensive spectroscopy was obtained at the Haute-Provence Observatory (OHP) with the ELODIE spectrograph on the 1.93-m telescope. Observations were collected during seven nights in 2003 (January 3-7 and January 11-15) and cover about 50 per cent of the close binary's (component A) orbital phase. The time exposure was fixed at 360s in order to resolve the presumed p-mode pulsations, yet with a good signal-to-noise ratio and a high resolution (about 50000).
