V originále
We present the development of collimated bipolar jets from the symbiotic prototype Z And during its 2006 outburst. We monitored spectroscopically and photometrically. The spectral properties of these satellite emissions indicated the ejection of bipolar jets collimated within an average opening angle. If the jets were expelled at the escape velocity, then the mass of the accreting white dwarf is MWD ~ 0.64 Msun. We estimated the average outflow rate via jets. During their lifetime, the jets released a total mass of M total jet ~ 7.4 x 10^-7 Msun. Evolution in the rapid photometric variability and asymmetric ejection of jets around the optical maximum can be explained by a disruption of the inner parts of the disk caused by radiation-induced warping of the disk.
