GALACTIC KINEMATICS OF PLANETARY NEBULAE WITH [WC] CENTRAL STAR

High resolution spectra are used to analyze the galactic kinematics and distribution of a sample of planetary nebulae with [WR] and 'wel' central star ([WR]PN and WLPN). The circular and peculiar velocities, (V-pec), of the objects were derived. The results are: (a) [WR]PNe are distributed mainly in the galactic disk and they are more concentrated in a thinner disk than WLPNe and normal PNe, which corresponds to a younger population. (b) The sample was separated in Peimbert's types, and it is found that Type I PNe have V-pec <= 50 km s(-1), indicating young objects. Most of the [WR]PNe are of Type II showing V-pec <= 60 km s(-1), although a small percentage is of Type III with larger V-pec. This shows that the Wolf-Rayet phenomenon in central stars can occur at any stellar mass and in old objects. None of our WLPNe is of Type I. Thus, [WR]PNe and WLPNe are unrelated objects.
