Orbital period change during the outburst of the symbiotic binary V 1329 Cygni
Abstract
Photographic photometry of the symbiotic nova V 1329 Cygni performed at the Skalnaté Pleso Observatory in the years 1979 1991 is presented. An observational proof of the 11 d .4 orbital period increase caused by the nova-like outburst around 1966 is given. New ephemeris valid after the year 1971 is as follows: JDmin = 2446784.862 + 963 d .306 ×E. The arguments in favour of accretion powered outburst are given.
