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. |
