Scientific paper

We present the first results of the ongoing project in which we observe spectroscopically bright β Cephei stars with the aim of seismic modelling of these stars. The spectroscopic data were collected with the Coudé spectrograph attached to the 2-m telescope at Rozhen Observatory. We present the first high-resolution (˜30,000) time-resolved spectra for KP Per and V986 Oph. They clearly show spectral line variations due to pulsations and have a quality sufficient to apply mode identification methods that take advantage of the shape of line profiles.
