J/A+A/531/A172      Central stars of planetary nebulae. II.   (Weidmann+, 2011)

Central stars of planetary nebulae: New OB-type and emission-line stars. Weidmann W.A., Gamen R. <Astron. Astrophys. 531, A172 (2011)> =2011A&A...531A.172W
ADC_Keywords: Planetary nebulae ; Spectral types ; Spectroscopy Keywords: surveys - planetary nebulae: general - atlases - stars: Wolf-Rayet Abstract: There are more than 3000 confirmed and probably known Galactic planetary nebulae (PNe), but central star spectroscopic information is available for only 13% of them. We have undertaken a spectroscopic survey of the central stars in PNe to identify their spectral types. We performed spectroscopic observations at low resolution with the 2-m telescope at CASLEO, Argentina. We present the spectra of 46 central stars of PNe, most of them are OB-type and emission-line stars. Description: We observed 46 PNs using the 2.15m telescope at Casleo, Argentina, between 2005 November and 2008 December. File Summary:
