Abstract

The published photometric and spectroscopic data of the symbiotic binary V 1329 Cyg are interpreted. It is shown, that V 1329 Cyg is an eclipsing binary with an elliptical orbit orbit (e=0.28). The cooler component fills up the Roche-lobe at periastron. A model of moving gaseous structures in the system is proposed and their influence on the radial velocity curve is shown. The following characteristics of the system are derived: the cooler component is an M6 giant with mass 7.9M⊙, radius 339R⊙ and luminosityMbol=−5.42, the hot component is a white dwarf surrounded by an accretion disk. The mean distance between the components is 842R⊙ and in periastron it decreases to 605R⊙.
