Definition of variability. Physical and geometrical variable stars. Pulsating and chemically peculiar stars. T Tauri stars Solar-type variability, pulsars. Binary stars (visual, spectroscopic, eclipsing, polarimetric). Roche model of close binary stars. Proximity effects in close binaries. Rossiter McLaughlin rotational effect. Mass loss and transfer. Secular effects (apsidal motion, circularization and synchronization of the orbit) Symbiotic stars. Cataclysmic variables. Supernovae. Mass accretion and accretion disks. Evolution of binary stars. Observational techniques of the stellar astronomy (photometry, spectroscopy, polarimetry, interferometry). Introduction to the photometric and spectroscopic data reduction. Time-series analysis, period analysis and the method of (O-C) diagrams.
Outcome:
Get acquainted with essential knowledge of variable stars classification and methods of their observations.
