摘要：
In March 2008 we obtained 2 nights of time-resolved high-resolution spectroscopy with UVES@VLT of the pulsating sdB QQ Vir (PG1325+101), totalling more than 750 spectra. We aim to study in detail the atmospheric response to the pulsations, and to derive observational constraints on the eigenmode of the main pulsation. In this paper we present the first preliminary results.
