Abstract:
The overlap between the spectroscopic Galactic Archaeology with HERMES
(GALAH) survey and Gaia provides a high-dimensional chemodynamical
space of unprecedented size. We present a first analysis of a subset
of this overlap, of 7066 turn-off, and sub-giant stars. These stars
have spectra from the GALAH survey and high parallax precision from
the Gaia DR1 Tycho-Gaia Astrometric Solution. We investigate
correlations between chemical compositions, ages, and kinematics for
this sample. Stellar parameters and elemental abundances are derived
from the GALAH spectra with the spectral synthesis code Spectroscopy
Made Easy. We determine kinematics and dynamics, including action
angles, from the Gaia astrometry and GALAH radial velocities. Stellar
masses and ages are determined with Bayesian isochrone matching, using
our derived stellar parameters and absolute magnitudes. We report
measurements of Li, C, O, Na, Mg, Al, Si, K, Ca, Sc, Ti, V, Cr, Mn,
Co, Ni, Cu, Zn, Y, as well as Ba and we note that we have employed
non-LTE calculations for Li, O, Al, and Fe. We show that the use of
astrometric and photometric data improves the accuracy of the derived
spectroscopic parameters, especially log g. Focusing our investigation
on the correlations between stellar age, iron abundance [Fe/H], and
mean alpha-enhancement [α/Fe] of the magnitude-selected sample,
we recover the result that stars of the high-α sequence are
typically older than stars in the low-α sequence, the latter
spanning iron abundances of -0.7<[Fe/H]<+0.5. While these two
sequences become indistinguishable in [α/Fe] vs. [Fe/H] at the
metal-rich regime, we find that age can be used to separate stars from
the extended high-alpha and the low-alpha sequence even in this
regime. When dissecting the sample by stellar age, we find that the
old stars (>8Gyr) have lower angular momenta Lz than the Sun, which
implies that they are on eccentric orbits and originate from the inner
disc. Contrary to some previous smaller scale studies we find a
continuous evolution in the high-alpha-sequence up to super-solar
[Fe/H] rather than a gap, which has been interpreted as a separate
'high-alpha metal-rich' population. Stars in our sample that are
younger than 10Gyr, are mainly found on the low alpha-sequence and
show a gradient in Lz from low [Fe/H] (Lz>Lz,☉) towards
higher [Fe/H] (Lz<Lz,☉), which implies that the stars at the
ends of this sequence are likely not originating from the close solar
vicinity.
Description:
In the following tables we give stellar parameters, stellar ages,
stellar masses, photometric parameters, astrometric parameters,
kinematical parameters, orbital parameters, and detailed elemental
abundances for Li, C, O, Na, Mg, Al, Si, K, Ca, Sc, Ti, V, Cr, Mn, Fe,
Co, Ni, Cu, Zn, Rb, Sr, Y, Zr, Mo, Ru, Ba, La, Ce, Nd, Sm, and Eu for
7066 main sequence and turn-off, and sub-giant stars observed by the
GALAH survey and overlapping with Gaia DR1 TGAS.
