Scientific paper

We present seven four-hour time series of high-resolution spectra of
theta Tucanae, a double-lined binary delta Scuti star with an unusual
mass ratio q=0.09. The spectra reveal line profile variations, and the
radial velocity varies with K_1=8.6 kms^{-1} for the principal pulsation
frequency f_1=20.27 cd^{-1}.
