    The Iron Abundance in Galactic Planetary Nebulae
    We constrain the iron abundance in a sample of 33 low-ionization Galactic planetary nebulae (PNe) using [Fe III] lines and correcting for the contribution of...

    The kinematic behaviour of optical recombination lines and collisionally excited lines in Galactic planetary nebulae*†
    The kinematics of the plasma in 14 planetary nebulae (PNe) is analysed by measuring the expansion velocities (Vexp) of different ions as derived from their...

    The kinematic structure of the unusual outflow source SH 2-71
    We have undertaken high resolution spectroscopy and IR photometry of the extended planetary nebula Sh 2-71. As a consequence, we note evidence for a discoidal...

    The kinematical behavior of Galactic PNe with [WC] central star
    High resolution spectroscopic data of a large sample of galactic planetary nebulae with [WC] central stars ([WC]PNe) are analyzed to determine their kinematical...

    The kinematical behavior of ORLs and CELs in PNe with [WC] central star
    In Planetary Nebulae (PNe) and HII regions ionic abundances can be derived by using collisionally excited lines (CELs) or recombination lines (ORLs). Such...

    The Kinematics and Dynamics of the Globular Clusters and Planetary Nebulae of NGC 5128
    A new kinematic and dynamic study of the halo of the giant elliptical galaxy NGC 5128 is presented. From a spectroscopically confirmed sample of 340 globular...

    The Kinematics of Point-symmetric Planetary Nebulae
    Four planetary nebulae (PNe) with conspicuous point-symmetric morphology are studied in this paper through high-quality imagery and long-slit echelle...

    The kinematics of the quadrupolar nebula M 1-75 and the identification of its central star
    Context. The link between how bipolar planetary nebulae are shaped and their central stars is still poorly understood. Aims: This paper investigates the...

    The Line-of-Sight Velocity Distributions of Intracluster Planetary Nebulae in the Virgo Cluster Core
    Radial velocities of 40 intracluster planetary nebulae (ICPNs) in the Virgo Cluster were obtained with the new multifiber FLAMES spectrograph on UT2 at the Very...
