HARPS Abundances with Korg I: 22 Element Abundances for 426 Red Giant Stars

Sarah E. Aquilina, Melissa Ness, Adam J. Wheeler +1

Large stellar surveys have revealed the global abundance structure of the Milky Way, but small high-fidelity spectral samples offer a critical complement of nucleosynthetic depth.…

Milky Way Mapper decoded abundances -- II: From patterns to paths

Melissa K. Ness, Sarah Aquilina, Jennifer Mead +15

The element abundances of Milky Way disc stars encode entangled imprints of multiple enrichment processes, making it difficult to uncover the underlying chemical evolution. Here we…

Milky Way Mapper decoded abundances -- I. Shared disc enrichment patterns

Melissa K. Ness, Sarah Aquilina, Jennifer Mead +15

Elemental abundances in the Milky Way disc trace its star-formation and enrichment history, but predicting these abundances from theory is limited by uncertain nucleosynthetic yiel…

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…

ACACIAS I: Element abundance labels for 192 stars in the dwarf galaxy NGC 6822

Melissa K. Ness, J. Trevor Mendel, Sven Buder +8

The element abundances of local group galaxies connect enrichment mechanisms to galactic properties and serve to contextualise the Milky Way's abundance distributions. Individual s…

The impact of incorrect dissociation energies on inferred photospheric abundances

Sarah E Aquilina, Andrew R Casey, Adam J Wheeler

Spectral synthesis codes are essential for inferring stellar parameters and detailed chemical abundances. These codes require many physical inputs to predict an emergent spectrum.…
