Detailed Abundance Determination of Metal-Poor Stars with X-Shooter II. - Chemically Disentangling the Halo, Disk and GSE

Benjamin D. C. Lowe, Luca Casagrande, Thomas Nordlander +2

We present a detailed chemical analysis of seven extremely metal-poor (EMP) star candidates observed with X-Shooter, combining them with 16 EMP candidates from Paper I. We measured…

HE0144-4657: A Carbon-Enhanced Ultra Metal-Poor Star ([Fe/H] ~ -4.1) from the Helmi Stream Disrupted Dwarf Galaxy

Vinicius M. Placco, Guilherme Limberg, Catherine R. Kennedy +1

We present the discovery of HE0144-4657, an ultra metal-poor, CNO-enhanced star dynamically associated with the Helmi Stream disrupted dwarf-galaxy remnant. This star was first ide…

Detailed Abundance Determination of Metal-Poor Stars with X-Shooter I. Unusual Chemistry in Halo Stars

Benjamin D. C. Lowe, Thomas Nordlander, Luca Casagrande +5

We present a detailed chemical analysis study of 16 candidate metal-poor stars, previously identified with 2dF + AAOmega, using X-Shooter spectra and the Korg 1D local thermodynami…

Unveiling the nature of HE 0107-5240

E. Caffau, M. Steffen, P. Molaro +27

The vast majority of the most iron-poor stars in the Galaxy exhibit a strong carbon enhancement, with C/H ratios only about two orders of magnitude below solar. This unusual chemic…

The Rise of the Milky Way Disk through EMP Stars

B. Lowe, T. Nordlander, L. Casagrande +6

We present a chemo-dynamical study conducted with 2dFAAOmega of Gaia DR3 non-variable candidate metal-poor stars that lie in the direction of the Galactic plane. Our…
