| Abstract: |
Using high-resolution spectroscopy, the double-lined spectroscopic binary with anomalous mass-ratio of 10, and the oscillations of theta Tuc are investigated. An indication for the binarity has already been given in Paparo et al. 1996. The spectrum of the more massive component of this binary shows line-profile variations. The radial-velocity variations present some of the pulsation frequencies found in the light variations by Paparo et al. 1996. References: Paparo, M., Steken, C., Spoon, H. W. W., Birch, P.
