We obtained time-resolved high-resolution spectroscopy of QQ Vir (B=13.5, main period=137.8 sec) with the ESO Very Large Telescope

  T_eff=35100 K, log(g)=5.74, log(N(He)/N(H))=-1.65

  The main-mode radial-velocity amplitude in Mar 2008 was 12 km/s.

  After folding to pulsational phase, the combined spectra have sufficient S/N for detailed analysis.

  We used cross-correlation to combine the pulsational information content of 12 carefully selected spectral lines into a single CCF

  From simple model fits (only 3D velocity field) to the pulsational line-profile variability in the CCFs, we aim to discriminate between possible L=0 and L=2 origin of the main mode in QQ Vir. Modes of L≥3 require unrealistic surface pulsation amplitudes and were hence not considered.

  The line-profile variability of the main mode of QQ Vir is best described by a model of a radial mode. Further detailed modeling of the line-profile variations is necesary to conclusively exclude an L=2 origin of the main mode.
