Cepheid investigations in the era of space photometric missions

Cepheid investigations in the era of space photometric missions

E. Plachy

Cepheid stars are crucial objects for a variety of topics that range from stellar pulsation and the evolution of intermediate-mass stars to understanding the structure of the Galaxy and the Universe through the distance measurements they provide. The developments in hydrodynamical calculations, the release of large ground-based surveys, and the advent of continuous, space-based photometry revealed many puzzling phenomena about these stars in the last few years. In this paper I have collected some important and new results on the topics of distance measurements and binarity investigations. I also summarize the most recent discoveries in their light variations, such as period doubling, modulation, low-amplitude additional modes, period jitter and the signs of granulation, and discuss the new opportunities that current and future space missions will offer for us.
