Abstract:
Gaia's third data release provides radial velocities for 33 million
stars and spectroscopically derived atmospheric parameters
for more than 5 million targets. When combined with the astrometric
data, these allow us to derive orbital and stellar parameters that are
key to understanding the stellar populations of the Milky Way and to
perform Galactic archaeology.
We used the calibrated atmospheric parameters, 2MASS and Gaia-EDR3
photometry, and parallax-based distances to compute the ages, initial
stellar masses, and reddenings for the stars with spectroscopic
parameters. We also derived the orbits for all of the stars with
measured radial velocities and astrometry, adopting two sets of
line-of-sight distances from the literature.
Four different sets of ages, masses, and absolute magnitudes in
different photometric bands are obtained through an isochrone fitting
method, considering different combinations of input parameters. The
reddenings are obtained by comparing the observed colours with those
obtained from the isochrone projection. Finally, the orbits are
computed adopting an axisymmetric potential of the Galaxy.
Comparisons with reference catalogues of field and cluster stars
suggest that reliable ages are obtained for stars younger than 9-10Gyr
when the estimated relative age uncertainty is <50 per cent. For older
stars, ages tend to be underestimated. The most reliable stellar type
for age determination are turn-off stars, even when the input
atmospheric parameters have large uncertainties. Ages for giants and
main-sequence stars are retrieved with uncertainties of the order of
2Gyr when extinction towards the star's line of sight is less than
AV≲2.5mag.
The catalogue of ages, initial stellar masses, reddenings,
galactocentric positions and velocities, as well as the stellar
orbital actions, eccentricities, apocentre, pericentre and maximum
distance from the Galactic plane reached during their orbits, is made
publicly available to be downloaded. With this catalogue, the full
chemo-dynamical properties of the extended solar neighbourhood unfold
and allow us to better identify the properties of the spiral arms, to
parametrise the dynamical heating of the disc, and to thoroughly study
the chemical enrichment of the Milky Way.
Description:
We build upon the Gaia public catalogues, and focus on the RVS sample
of GDR3. This sample contains 33*106 stars with radial velocity
measurements and 5*106 stars with spectroscopic parameters and
abundances (Recio-Blanco et al., 2022, arXiv:2206.05541; Fouesneau et
al., 2022, arXiv:2206.05992). We performed an improved projection on
the isochrones that takes into account the necessary GSP-Spec
calibrations of metallicity and surface gravities2, stellar distance
(in a different way to FLAME, using the Bailer-Jones et al. (2021,
Cat. I/352) values), infrared (2MASS, Skrutskie et al., 2006, Cat.
VII/233), and EDR3 photometry. Furthermore, for the community's
convenience, we also computed and provide the catalogue of the
three-dimensional galactocentric positions, (cylindrical) velocities,
and orbital parameters of all of the GDR3 RVS stars using an updated
version of the axisymmetric Galactic potential of McMillan
(2017MNRAS.465...76M 2017MNRAS.465...76M) and the Galpy code (Bovy, 2015ApJS..216...29B 2015ApJS..216...29B).
