Abstract:
Central stars of planetary nebulae (CSPNe) are essential for
understanding the final evolutionary stages of low- and
intermediate-mass stars. 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.
Description:
The main objective of this work is to compile known properties of
extragalactic CSPNe, including the spectral type, luminosity and
effective temperature. The catalogue includes 864 objects
across 19 galaxies.
