Misclassified and Misidentified Planetary Nebulae and Nuclei

Publications of the Astronomical Society of the Pacific, 1983
Observations are reported for 17 objects that are listed in the Catalogue of Galactic Planetary Nebulae (CGPN). These have either been misclassified as planetary nebulae, have been identified incorrectly by their observers or in the CGPN, or have had peculiar central stars erroneously assigned to them.

Nuclei of Planetary Nebulae and White Dwarf Envelopes

Astrophysics and Space Science, 1973
Upper bounds to the masses of He envelopes of white dwarfs are derived by examining the maximum He envelope that a nucleus of a planetary nebulae can have consistent with observation.

The Nuclei of Planetary Nebulae

Publications of the Astronomical Society of Australia, 1967
For some years now, there have been suggestions that the nuclei of planetary nebulae are stars undergoing a final gravitational contraction to the white dwarf state. These have culminated in two important studies by O’Dell, and by Seaton and his collaborators, the results of which are indicated on the Hertzsprung-Russell diagram of Figure 1.

The Evolution of the Nuclei of Planetary Nebulae

Publications of the Astronomical Society of Australia, 1972
In the past decade, planetary nebulae have assumed considerable importance in elucidating our understanding of the final stages of stellar evolution at low mass. This began with the work of Shklovsky, O’Dell and Seaton, who showed not only that the nuclei of these nebulae were among the hottest stellar objects, but also that they evolved on a track in ...

Galactic planetary nebulae and evolution of their nuclei

Astrophysics, 1980
The galactic system of planetary nebulae is investigated using previously constructed distance scale and kinematics data. A strong effect of observational selection is established, which has the consequence that with increasing distance, ever brighter and younger objects are observed. More accurate determinations of the spatial and surface densities of
