Pre- and Post-Outburst Parameters for the Components of the Symbiotic Star V1329 Cyg

We present new UBV observations of the symbiotic nova V1329 Cyg. Based on all our UBV observations of a uniform system, we redetermined the orbital period of the binary and estimated the magnitudes and luminosities of its components. We show that the pre-outburst visual luminosities of the red giant and the hot star were almost equal and that the rapid irregular photographic variability of the star was caused by the nonstationary behavior of the hot component. The outburst amplitude of the hot component (subdwarf) in 1964 was found to be ~2 mag in the V band, which is typical of ordinary symbiotic stars. We estimated the continuum luminosity of the gaseous component that appeared after the outburst. In the V band, it was almost 1 mag fainter than the flared hot star. Structurally, the gaseous component is an ionized gaseous disk comparable in size to an M giant.
