Abstract:
The characteristics of the stellar populations in the Galactic bulge
inform and constrain the Milky Way's formation and evolution. The
metal-poor population is particularly important in light of
cosmological simulations, which predict that some of the oldest stars
in the Galaxy now reside in its centre. The metal-poor bulge appears
to consist of multiple stellar populations that require dynamical
analyses to disentangle. In this work, we undertake a detailed
chemodynamical study of the metal-poor stars in the inner Galaxy.
Using R ∼ 20 000 VLT/GIRAFFE spectra of 319 metal-poor
(-2.55dex≤[Fe/H]≤0.83dex, with mean [Fe/H]=-0.84dex) stars, we
perform stellar parameter analysis and report 12 elemental abundances
(C, Na, Mg, Al, Si, Ca, Sc, Ti, Cr, Mn, Zn, Ba, and Ce) with
precisions of ∼0.10 dex. Based on kinematic and spatial properties,
we categorize the stars into four groups, associated with the
following Galactic structures: the inner bulge, the outer bulge, the
halo, and the disc. We find evidence that the inner and outer bulge
population is more chemically complex (i.e. higher chemical
dimensionality and less correlated abundances) than the halo
population. This result suggests that the older bulge population was
enriched by a larger diversity of nucleosynthetic events. We also find
one inner bulge star with a [Ca/Mg] ratio consistent with theoretical
pair-instability supernova yields and two stars that have chemistry
consistent with globular cluster stars.
