Planetary Nebulae: Individual: Ngc 5189
Scientific paper
Archival high-and low-dispersion IUE spectra of NGC 5189 and its central star were reexamined. It was found that earlier published results misinterpreted nebular features for stellar emission lines due to incorrect coordinates and/or incorrect pointing of the spacecraft. NGC 5189 has a UV spectrum rich in emission lines of He II, C II], C III, C III], C IV, C V, N III], N IV], O I, O III], O IV], O V, O VI, O VII, O VIII, [Ne III], [Ne IV], [Ne V], [Mg V], [Ar IV], Si III], and Fe II. The data were reextracted and the emission line fluxes were measured. Electron density for C III] and terminal wind velocities from C IV P Cygni profiles were determined. Comparisons of the IUE spectra of NGC 5189 and NGC 6905 show that these objects have very similar characteristics. (SECTION: Interstellar Medium and Nebulae)
