Scientific paper

Narrow band continuum images of 21 planetary nebulae were obtained using a CCD camera at the prime focus of the Anglo-Australian Telescope. The nebulae were selected on the basis that their central stars were previously poorly detected or undetected. The images were used to determine visual magnitude for the nuclei of the planetary nebulae and calculate their corresponding Zanstra temperatures. The distribution of the planetary nebulae on the Log L-Log T plane is discussed in terms of theories of the evolution of the nuclei of planetary nebulae. A number of the central stars studied have high temperatures which can be explained with present theories if their masses are 1 solar mass.
