Abstract:
We have compiled a catalogue of central stars of planetary nebulae
(CSPN) with reliable distances and positions obtained from Gaia Data
Release 2 (DR2) astrometry. Distances derived from parallaxes allow us
to analyse the galactic distribution and estimate other parameters
such as sizes, kinematical ages, bolometric magnitudes, and
luminosities.
Our objective is to analyse the information regarding distances
together with other available literature data about photometric
properties, nebular kinematics, and stellar effective temperatures to
throw new light on this rapid and rather unknown evolutionary phase.
We seek to understand how Gaia distances compare with other indirect
methods commonly used and, in particular, with those derived from
non-local thermodynamic equilibrium (non-LTE) models; how many
planetary nebulae (PNe) populate the Galaxy; and how are they
spatially distributed. We also aim to comprehend their intrinsic
luminosities, range of physical sizes of the nebulae; how to derive
the values for their kinematical ages; and whether those ages are
compatible with those derived from evolutionary models.
We considered all PNe listed in catalogues from different authors and
in Hong Kong/AAO/Strasbourg/Hα (HASH) database. By X-matching
their positions with Gaia DR2 astrometry we were able to identify 1571
objects in Gaia second archive, for which we assumed distances
calculated upon a Bayesian statistical approach. From those objects,
we selected a sample of PNe with good quality parallax measurements
and distance derivations, we which refer to as our Golden Astrometry
PNe sample (GAPN), and obtained literature values of their apparent
sizes, radial and expansion velocities, visual magnitudes,
interstellar reddening, and effective temperatures.
We found that the distances derived from DR2 parallaxes compare well
with previous astrometric derivations of the United States Naval
Observatory and Hubble Space Telescope, but that distances inferred
from non-LTE model fitting are overestimated and need to be carefully
reviewed. From literature apparent sizes, we calculated the physical
radii for a subsample of nebulae that we used to derive the so-called
kinematical ages, taking into account literature expansion velocities.
Luminosities calculated with DR2 distances were combined with
literature central stars Teff values in a Hertzsprung-Russell (HR)
diagram to infer information on the evolutionary status of the
nebulae. We compared their positions with updated evolutionary tracks
finding a rather consistent picture. Stars with the smallest
associated nebular radii are located in the flat luminosity region of
the HR diagram, while those with the largest radii correspond to
objects in a later stage, getting dimmer on their way to become a
white dwarf. Finally, we commented on the completeness of our
catalogue and calculated an approximate value for the total number of
PNe in the Galaxy.
Description:
In this table, astrometric parameters for a set of 211 planetary
nebulae with realiable distances estimations in Gaia DR2 (the Golden
Astrometry Planetary Nebulae sample (GAPN)), are presented.
Additionally to distances and their errors it lists identifications,
coordinates, parallaxes, galactic heights, radii, and radial
velocities of the planetary nebulae.
