J/A+A/403/659       Classification of WR planetary nebulae   (Acker+, 2003)

Quantitative classification of WR nuclei of planetary nebulae. Acker A., Neiner C. <Astron. Astrophys. 403, 659 (2003)> =2003A&A...403..659A
ADC_Keywords: Planetary nebulae ; Stars, Wolf-Rayet ; Line Profiles Keywords: planetary nebulae: general - stars: evolution - stars: AGB and post-AGB - stars: Wolf-Rayet - line: profiles Abstract: We analyse 42 emission-line nuclei of Planetary Nebulae (PNe), in the framework of a large spectrophotometric survey of [WC] nuclei of PNe conducted since 1994, using low/medium resolution spectra obtained at ESO and at OHP. We construct a grid of selected line-intensities (normalized to C IV-5806Å=100) ordered by decreasing ionisation potential going from 871 to 24eV. In this grid, the stars appear to belong clearly to prominent O (hot [WO1-4] types) or C (cooler [WC4-11] types) line-sequences, in agreement with the classification of massive WR stars applied to Central Stars of Planetary Nebulae (CSPNe) by Crowther et al. (1998MNRAS.296..367C, CMB98). We propose 20 selected line ratios and the FWHM of CIV and CIII lines as classification diagnostics, which agree well with the 7 line ratios and the FWHM proposed by CMB98. File Summary:

Note (1): The PN labelled with 'S' belongs to the Sagittarius dwarf galaxy. Note (2): Spectral classes marked with *: classification based on observations obtained at OHP (1993-2000, see Sect. 2). *1: visual inspection on ``Pediscou'' plates, obtained at OHP (tel. 1.93m), in June 1974 with an exposure time of 15 min. *2: visual inspection on `electronic camera' plates, obtained at OHP (tel. 1.93m), in 1961, by M. Chopinet (private com.).
