Abstract:
We present a comprehensive overview of a volume-complete sample of
white dwarfs located within 40 pc of the Sun, a significant proportion
of which were detected in Gaia Data Release 3 (DR3). Our DR3 sample
contains 1073 spectroscopically confirmed white dwarfs, with just 8
candidates within our volume remaining unconfirmed (99.3 per cent
spectroscopic completeness). Additionally, 28 white dwarfs were not in
our initial selection from Gaia DR3, most of which are in unresolved
binaries. We use Gaia DR3 photometry and astrometry to determine a
uniform set of white dwarf parameters, including mass, effective
temperature, and cooling age. We assess the demographics of the 40 pc
sample, specifically magnetic fields, binarity, space density and mass
and age distributions.
Description:
Table A1 presents all confirmed white dwarfs within 40pc of the Sun,
with accurate photometric parameters as well as spectral types and
references.
Table A6 is a wide binary catalogue with all wide binaries within 40pc
that contain at least one white dwarf.
