Hydrodynamical models of planetary nebulae with [WC] central stars

High-resolution, long-slit spectroscopic observations of two planetary nebulae, M1-32 and M3-15 are presented. 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, M3-15 has two very faint high-velocity knots. To model M1-32 and M3-15 we built a 3D model consisting in a jet interacting with an equatorially concentrated slow wind, emulating the presence of a dense torus, by using the hydrodynamical code Yguazú. Spectroscopically we find that both M 3-15 and M 1-32 show a torus and high-velocity bipolar ejections. Therefore, we propose to call them ‘spectroscopic bipolar nebulae’. Our models are good agreement with the observations.
