Abstract:
We produce a clean and well-characterised catalogue of objects within
100 pc of the Sun from the Gaia Early Data Release 3. We characterise
the catalogue through comparisons to the full data release, external
catalogues, and simulations. We carry out a first analysis of the
science that is possible with this sample to demonstrate its potential
and best practices for its use.
The selection of objects within 100 pc from the full catalogue used
selected training sets, machine-learning procedures, astrometric
quantities, and solution quality indicators to determine a probability
that the astrometric solution is reliable. The training set
construction exploited the astrometric data, quality flags, and
external photometry. For all candidates we calculated distance
posterior probability densities using Bayesian procedures and mock
catalogues to define priors. Any object with reliable astrometry and a
non-zero probability of being within 100pc is included in the
catalogue.
We have produced a catalogue of 331312 objects that we estimate
contains at least 92% of stars of stellar type M9 within 100pc of the
Sun. We estimate that 9% of the stars in this catalogue probably lie
outside 100pc, but when the distance probability function is used, a
correct treatment of this contamination is possible. We produced
luminosity functions with a high signal-to-noise ratio for the
main-sequence stars, giants, and white dwarfs. We examined in detail
the Hyades cluster, the white dwarf population, and wide-binary
systems and produced candidate lists for all three samples. We
detected local manifestations of several streams, superclusters, and
halo objects, in which we identified 12 members of Gaia Enceladus. We
present the first direct parallaxes of five objects in multiple
systems within 10pc of the Sun.
We provide the community with a large, well-characterised catalogue of
objects in the solar neighbourhood. This is a primary benchmark for
measuring and understanding fundamental parameters and descriptive
functions in astronomy.
Description:
We produce a clean and well characterised catalogue of nearby objects
within 100pc of the Sun from the Gaia early third data release. We
characterise the catalogue using the full data release, and
comparisons to other catalogues in literature and simulations. We
started with a sample of objects with a measured parallax of 8mas. For
all candidates we calculate a distance probability function using
Bayesian procedures and mock catalogues for the prediction of the
priors. For each entry using a random forest classifier we attempt to
remove sources with spurious astrometric solutions.
From this paper we provide the following data files:
table1c.dat (Table1GCNScat): Any object with a non-zero probability
of being within 100 pc and not indicated as a spurious astrometric
solutions. We have also included external photometric and radial
velocity data, the probability of reliable astrometry, probability to
be a white dwarf, the distance 1st, 16th, 50th and 84th percentiles,
the positions and velocities in a galactic reference frame. For
questions please email richard.smart(at)inaf.it.
table1r.dat (Table1GCNSreject): All other entries from the 8mas
sample that were rejected as having a zero probability of being inside
100pc or indicated as a spurious astrometric solution. This table has
the same format and columns as GCNS_cat.dat.
progwd.dat (ProbWDlt05_ProbGFgt05): A catalogue of 45 sources with low
probability of being a WD in this work (PWD<0.5), but having larger
probabilities in Gentile-Fusillo et al (2019MNRAS.482.4570G 2019MNRAS.482.4570G, cat.
J/MNRAS/482/4570) (PGF>0.5). For questions please email
carrasco(at)fqa.ub.edu.
table3.dat (Table3_ResolvedStellarSystems): Resolved binary candidates
in the GCNS catalogue as discussed in the section on stellar
multiplicity: resolved systems. For questions please email
ummi.abbas(at)inaf.it or alessandro.sozzetti(at)inaf.it.
maglim.dat (maglimhpx5percentile): The magnitude percentiles for
level 5 healpixels used in the luminosity function determinations. For
questions please email rybizki(at)mpia.de.
distpdf.dat (distance_PDF): The full distance probability density
function calculated in section 2 and used throughout the paper. For
questions please email rybizki(at)mpia.de.
missing.dat (missing_10mas): A list of 1258 objects with published
parallaxes greater than 10mas that are not or have no parallax in
EDR3. For questions please email celine.reyle(at)obs-besancon.fr.

members in the GCNS sample. For questions please email

Note (1): Dimensionless chi-square test statistic. Small values indicate highly
probable members. See Reino et al. 2018MNRAS.477.3197R 2018MNRAS.477.3197R, Eq. (4).
Note (2): Distance of each star from the cluster barycentre, using (XCOORD_50,
YCOORD_50, ZCOORD_50) from GCNS_cat.dat. The cluster barycentre is computed
as the average (X, Y, Z) coordinate of all stars in the central region of the
cluster (two tidal radii), assuming equal masses for all stars.
