NAZOV / TITLE :

Eclipsing binary stars - an adventure

ABSTRAKT / ABSTRACT :

Eclipsing binaries are proving to be powerful tools for studying a wide spectrum of astrophysical problems.

I will present different types of eclipsing binaries connected with my work. We have come to a conclusion that 
merges previously contradictory opinions on post-common eclipsing binary V471 Tau behaviour. We explained 
the eclipse timing variability of V471 Tau by the magnetic cycle of its K2 V red dwarf secondary and the 
simultaneous presence of a third component - a brown dwarf.
I will also mention the significant upgrade/progress in the Dwarf project - an eclipse variability study 
on ~50 dwarf binaries and an investigation of symbiotic binary BF Cyg in a long active phase.
