Abstract:
The solar vicinity is currently populated by a mix of stars with
various chemo-dynamical properties, including stars with a high
metallicity compared to the Sun. Dynamical processes such as churning
and blurring are expected to relocate such metal-rich stars from the
inner Galaxy to the Solar region.
We report the identification of a set of old super metal-rich
(+0.15≤[Fe/H]≤+0.50) dwarf stars with low eccentricity orbits
(e≲0.2) that reach a maximum height from the Galactic plane
between ∼0.5-1.5kpc. We discuss their chemo-dynamical properties
with the goal of understanding their potential origins.
We use data from the internal data release 6 of the Gaia-ESO Survey. We
selected stars observed at high resolution with abundances of 21 species of
18 individual elements (i.e., 21 dimensions). We apply a hierarchical
clustering algorithm to group the stars with similar chemical abundances
within the complete chemical abundance space. Orbits were integrated using
astrometric data from Gaia and radial velocities from Gaia-ESO. Stellar ages
were estimated using isochrones and a Bayesian method.
According to their chemical properties, this set of super metal-rich
stars can be arranged into five subgroups. Four of them seem to follow
a chemical enrichment flow, where nearly all abundances increase in
lockstep with Fe. The fifth subgroup shows different chemical
characteristics. All subgroups have the following features: median
ages of the order of 7-9 Gyr (with five outlier stars of estimated
younger age), Solar or sub-Solar [Mg/Fe] ratios, maximum height from
the Galactic plane between 0.5-1.5kpc, low eccentricities
(e≲0.2), and a detachment from the expected metallicity gradient with
guiding radius (which varies between ∼6 to 9kpc for the majority of
the stars).
The high metallicity of our stars is incompatible with a formation in the
Solar neighbourhood. Their dynamic properties agree with theoretical
expectations that these stars travelled from the inner Galaxy due to
blurring and, most importantly, to churning. We, therefore, suggest that
most of the stars in this population originated in the inner regions of the
Milky Way (inner disc and/or the bulge) and later migrated to the Solar
neighbourhood. The region from where the stars originated had a complex
chemical enrichment history, with contribution from supernovae types Ia and
II, and possibly asymptotic giant branch stars as well.
Description:
The table lists the chemo-dynamic parameters for the most metal rich
stars used in the paper.

Note (2): all the columns after (and including) 'angmomentxlxmean' are
estimated through running galpy (Bovy, 2015ApJS..216...29B 2015ApJS..216...29B) in the resampled
data for each star (100 resamples).
Note (3): Columns with 'lsr' indicate that it is in the Local Standard of Rest.
