Abstract

The results of study of the classical symbiotic star Z And during the recent activity period that began in 2000 are presented. Up to now series of six outbursts took place. Comparison of observational data with the results of gasdynamic modeling allow us to suggest the possible scenario for activity in this system describing all stages of an outburst development—from the mechanism of transition to the outburst and outburst development to the behavior of the system during all the activity period. Particularly, the proposed scenario explains the principal difference between outbursts—the presence of high-velocity bipolar collimated optical outflows in strong recurring outbursts. We have not found contradictions with the available data for previous outbursts of Z And. We assume that the proposed scenario could be also typical for other classic symbiotic stars. In order to check and improve our model additional observations are highly desirable and the UV spectral range could provide us with very useful data.
