Scientific paper

Luminosities and temperatures have been derived for 11 nuclei of stellar planetary nebulae using measurements of the stellar visual monochromatic magnitudes, H beta fluxes and angular diameters of the nebulae. In the HR-diagram the central stars are located near the Harman-Seaton sequence for planetary nebulae. However, within the group of young planetaries there exist large differences in the luminosities of the nuclei as well as in the physical parameters of the associated nebulae.
