Abstract:
The nearest stars provide a fundamental constraint for our
understanding of stellar physics and the Galaxy. The nearby sample
serves as an anchor where all objects can be seen and understood with
precise data. This work is triggered by the most recent data release
of the astrometric space mission Gaia and uses its unprecedented high
precision parallax measurements to review the census of objects within
10pc.
The first aim of this work was to compile all stars and brown dwarfs
within 10pc observable by Gaia and compare it with the Gaia Catalogue
of Nearby Stars as a quality assurance test. We complement the list to
get a full 10 pc census, including bright stars, brown dwarfs, and
exoplanets.
We started our compilation from a query on all objects with a parallax
larger than 100 mas using the Set of Identifications, Measurements,
and Bibliography for Astronomical Data database (SIMBAD). We completed
the census by adding companions, brown dwarfs with recent parallax
measurements not in SIMBAD yet, and vetted exoplanets. The compilation
combines astrometry and photometry from the recent Gaia Early Data
Release 3 with literature magnitudes, spectral types, and
line-of-sight velocities.
We give a description of the astrophysical content of the 10pc sample.
We find a multiplicity frequency of around 27%. Among the stars and
brown dwarfs, we estimate that around 61% are M stars and more than
half of the M stars are within the range from M3.0 V to M5.0 V. We
give an overview of the brown dwarfs and exoplanets that should be
detected in the next Gaia data releases along with future
developments.
We provide a catalogue of 541 stars, brown dwarfs, and exoplanets in
339 systems, within 10pc from the Sun. This list is as volume-complete
as possible from current knowledge and it provides benchmark stars
that can be used, for instance, to define calibration samples and to
test the quality of the forthcoming Gaia releases. It also has a
strong outreach potential.
Description:
We provide a catalogue of 541 stars, brown dwarfs, and exoplanets in
339 systems, within 10 pc from the Sun. Astrometry, photometry,
spectral types, and line-of-sight velocities are given when available.
This list is as volume-complete as possible from current knowledge and
provides benchmark stars that can be used, for instance, to define
calibration samples and to test the quality of the forthcoming Gaia
releases. It also has a strong outreach potential.
Table A1 was updated on 06-Feb-2023.
This work is an update of the 10pc sample that used the unprecedented
high precision parallax measurements from the early third data release
of the astrometric space mission Gaia. We review this census, all
updates being related to close binaries, brown dwarfs and exoplanets.
We provide a new catalogue of 541 stars, brown dwarfs, and exoplanets
in 336 systems within 10 pc from the Sun. This list is as
volume-complete as possible from current knowledge and it provides a
list of benchmark stars. We also explore the new products made
available in the most recent third Gaia data release.
The catalogue contains 541 stars, brown dwarfs, and exoplanets in 354
systems, closer than 10pc from the Sun.
