Expansion velocities of selected PNe
Published online by Cambridge University Press: 30 August 2012
Abstract
In order to clarify the observed relation between the expansion velocity measured from lines of different ions and their ionization potential, we present kinematical data for several objects. We have measured radial velocities on ESO UVES high dispersion spectra to compare expansion velocities for a set of planetary nebulae.
