Project superfast LPV

The project superfast LPV (Line Profile Variability) is aimed to study the variation of the line profiles in the spectra of early-type stars at the short time scale from seconds to hours. We analysed both the observation on the large telescopes as 6-meter telescope BTA in the Special Astrophysical Observatory (Russia), 8-meter telescopes VLT in ESO (Chile) with spectrographs and spectropolarimeters of low or moderate resolving power as SCORPIO and FORS 2 to study the fast line profile changes with the high signal to noise ratio and the moderate size telescopes. The project includes the list of atomic lines in the spectra of OBA stars; the list of targets can be used for looking for the superfast LPV at minutes and seconds scales and the results of our observations. In a future we plan to additionally use other telescopes for looking for the superfast LPVs.
