Abstract:
Planetary nebulae represent a potential late stage of stellar
evolution, however, their central stars (CSPNe) are relatively faint
and, therefore, pertinent information is available for merely <20% of
the Galactic sample.
Consequently, the literature was surveyed to construct a new catalogue
of 620 CSPNe featuring important spectral classifications and
information.
The catalogue supersedes the existing iteration by 25% and includes
physical parameters such as luminosity, surface gravity, temperature,
magnitude estimates, and references for published spectra.
The marked statistical improvement enabled the following pertinent
conclusions to be determined: the H-rich/H-poor ratio is 2:1, there
is a deficiency of CSPNe with types [WC 5-6], and nearly 80% of binary
central stars belong to the H-rich group.
The last finding suggests that evolutionary scenarios leading to the
formation of binary central stars interfere with the conditions
required for the formation of H-poor CSPN.
Approximately 50% of the sample with derived values of logL,
logTeff, and logg, exhibit masses and ages consistent with single
stellar evolutionary models.
The implication is that single stars are indeed able to form planetary
nebulae.
Moreover, it is shown that H-poor CSPNe are formed by higher mass
progenitors.
Description:
The catalogue include 620 CSPNe with spectral type, references for
published spectra, magnitude, logL, logTeff, and logg.
