Eclipsing variables

Eclipsing variables are observed on regularly basis in our workgroup. Some eclipsing binaries are observed visually but most of the observers of the workgroup observe them with CCD. The results are regularly published. (See HADS-project).

Eclipsing variables are binaries that are oriented in such a way that one component can eclipse the other. Consequently, we receive less light of the system. Such an eclipse can last a few hours, although other binaries take days to complete an eclipse. The best known eclipsing variable is Algol (Bèta Per).
With the exception of the Type II supernovae all other subtypes belonging to the cataclysmic variables are also binaries. Some of these stars also show eclipses.
