Tipsy pulsation of classical Cepheids – lessons from space photometry

Space photometric data of the Kepler Cepheid, V1154 Cygni, and those of SZ Tauri (MOST photometry) indicate that classical Cepheids are not strictly regular pulsators. Cycle-to-cycle period changes and variations in the shape of the light curve are revealed from the continuous photometry covering 6...
