Well-defined astrophysical constraints of white dwarfs (WDs), such as on the presence or absence of pulsational variability, are very much needed to refine and develop current models. Because these stars are rather faint and variability periods are m

The central stars of planetary nebulae are interesting objects which are important to understand the very late stages of stellar evolution. They exhibit variability due to binarity, stellar winds, and pulsation. We searched for variability in five of

The project of time series analysis for the photometric observations of a representative group of RV Tauri type stars is described. This class of variables consists of about 100 supergiants in the Milky Way. Their light curves show in general two une

The chemically peculiar (CP) stars of the upper main sequence are perfect tracers for several astrophysical processes.Their study especially in open clusters further helps to establish their evolutionary status. The latter is most important tounderst
