Hydrodynamical models of planetary nebulae with [WC] central stars

We present high-resolution, long-slit spectroscopic observations for the planetary nebulae, M1-32, M3-15. The observations were obtained with the 2.1-m telescope at the OAN- SPM, and MES spectrograph. M1-32 shows wide wings on the base of its emission lines at high velocity, M3-15 has two very faint high-velocity knots. To model M1-32 and M3-15 we built a 3D model using the hydrodynamical code Yguazú. Our model consisting in a jet interacting with an equatorially concentrated slow wind, emulating the presence of a dense torus. We propose to classify this kind of objects as spectroscopic bipolar nebulae, due to the bipolar morphology only is observed using spectroscopy.
