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…
A Main Sequence CH-star in the globular cluster M55 (NGC 6809)
G. S. Da Costa, T. Nordlander
Spectra have been obtained with multi-fibre instrument 2dF on the Anglo-Australian Telescope of 89 candidate main sequence stars in the globular cluster M55 (NGC 6809). Radial velo…
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…
The GALAH Survey: Data Release 4
S. Buder, J. Kos, E. X. Wang +36
The stars of the Milky Way carry the chemical history of our Galaxy in their atmospheres as they journey through its vast expanse. Like barcodes, we can extract the chemical finger…
A panoramic view of the Local Group dwarf galaxy NGC 6822
Shumeng Zhang, Dougal Mackey, Gary Da Costa
We present a panoramic survey of the isolated Local Group dwarf irregular galaxy NGC 6822. Our photometry reaches magnitudes deeper than most previous studies and spans t…
High resolution spectroscopic follow-up of the most metal-poor candidates from SkyMapper DR1.1
D. Yong, G. S. Da Costa, M. S. Bessell +13
We present chemical abundances for 21 elements (from Li to Eu) in 150 metal-poor Galactic stars spanning 4.1 [Fe/H] 2.1. The targets were selected from the SkyMapper…
