Central stars of extragalactic PNe
Listed in IVOA Registry (Virtual Observatory)
Central stars of planetary nebulae (CSPNe) are essential for understanding the final evolutionary stages of low- and intermediate-mass stars.
Description
However, their study in extragalactic environments remains challenging due to their intrinsic faintness and the limited availability of high-quality data. We aim to provide a comprehensive and up-to-date catalogue of extragalactic CSPNe, enabling a more complete view of their physical properties across different galactic environments and metallicities.
The catalogue was assembled using data from the most recent and reliable literature sources. Priority was given to collecting effective temperatures and luminosities, either directly reported or consistently derived. When available, spectral types or specific spectral features - such as P-Cygni profiles or broad Halpha emission lines - were also included.

This approach allows for a broader characterization of the sample, even when accurate classifications are not available. We present a new compilation of extragalactic CSPNe - the largest to date - comprising over 1000 objects located in the Magellanic Clouds, NGC 300, NGC 5128, and other fifteen nearby galaxies. This catalogue enables, for the first time, a global comparison of CSPNe physical parameters beyond the Milky Way.
Updated Hertzsprung-Russell diagrams are provided, featuring CSPNe from seven different galaxies, revealing trends and outliers that merit further investigation. The catalogue represents a valuable resource for future spectroscopic follow-up and for improving our understanding of post-AGB evolution in diverse galactic contexts.
