Galactic Planetary Nebulae with Wolf-rayet Nuclei Iii. Kinematical Analysis of a Large Sample of Nebulae

Abstract

Expansion velocities (Vexp) of different ions and line widths at the base of the lines are measured and analyzed for 24 PNe with [WC]-type nuclei (WRPNe), 9 PNe ionized by WELS (WLPNe) and 14 ordinary PNe. A comparative study of the kinematical behavior of the sample clearly demonstrates that WRPNe have in average 40-45% larger Vexp, and possibly more… (More)
