Abstract: Eclipsing binary systems offer a unique possibility to study in detail the structure and evolution of their components. Such a study is even more important if one of the components is a pulsating star. Being able to measure very precisely the physical parameters of the pulsator allows us, for example, to test predictions of pulsation and evolution theories. Cepheids are also very well-known and widely used as distance indicators. Having a Cepheid in a binary system gives us the opportunity to test, compare and calibrate three independent distance determination methods: the period–luminosity relation, Baade–Wesselink method, and the eclipsing binary method. Up to now, we have analyzed seven Cepheids in six eclipsing binary systems, measuring their masses and projection factors. I present the newest results of our analysis together with a brief description of the modeling.
