The Metal-Line Spectra of Central Stars of Planetary Nebulae
Published online by Cambridge University Press: 19 July 2016
Abstract
We present spectral descriptions based on high-resolution spectrograms of central stars of planetary nebulae, obtained with the ESO 3,6-m telescope + CASPEC (Cassegrain Echelle Spectrograph). We make preliminary determinations of stellar photospheric metal abundances, using non-LTE model atmospheres and non-LTE line formation calculations.
