Abstract: We discuss our new (Teodorani et al. 1997) and already published photometric and spectroscopic data regarding the binary system Z CMa and conclude that these data, in contrast to wide spread opinion, do not contradict the hypotesis that a FU On type secondary rather than the IR primary is the main source of the observed optical variations and outflow. In the frame of this hypothesis, we explain observed larger polarization in the emission lines than in the continuum as a result of Thomson scattering of line quanta inside the region of their formation.
