Scientific paper

The authors present monochromatic blue magnitudes, spectral descriptions and non-LTE model atmosphere analyses of several central stars of planetary nebulae (CSPN). The analyses yield the Teff, log g and He abundances in the atmospheres of these stars. The authors have found new examples of H-deficient central stars: K1-27, Longmore 3 and Longmore 4. The observed positions of 12 CSPN on the log g - log Teff diagram are compared with theoretical post-AGB evolutionary tracks.
