J/A+A/463/265  Chemical compositions of 48 WR planetary nebulae  (Girard+, 2007)

Chemical compositions and plasma parameters of planetary nebulae with Wolf-Rayet and wels type central stars. Girard P., Koeppen J., Acker A. <Astron. Astrophys. 463, 265 (2007)> =2007A&A...463..265G
ADC_Keywords: Planetary nebulae ; Abundances Keywords: planetary nebulae: general - stars: abundances - stars: evolution - stars: Wolf-Rayet - stars: AGB and post-AGB Abstract: Chemical compositions and other properties of planetary nebulae around central stars of spectral types [WC], [WO], and wels are compared with those of "normal" central stars, in order to clarify the evolutionary status of each type and their interrelation. We use plasma diagnostics to derive from optical spectra the plasma parameters and chemical compositions of 48 planetary nebulae. We also reanalyze the published spectra of a sample of 167 non-WR PN. The results as well as the observational data are compared in detail with those from other studies of the objects in common. File Summary:
