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…
The complex stellar system M 22: constraining the chemical enrichment from AGB stars using magnesium isotope ratios
M. McKenzie, D. Yong, A. I. Karakas +8
The paper measures magnesium isotope ratios in the globular‑cluster-like system M 22 and finds that low‑mass (1–3 M☉) AGB stars can explain its s‑process enrichment, while higher‑m…
The impact of stellar binaries and star cluster dynamics on pair-instability supernovae
Francesco Gabrielli, Cristiano Ugolini, Lavinia Paiella +12
Pair-instability supernovae (PISNe) are among the most luminous transients in the Universe. However, they have never been confidently observed. Solving this puzzle would have key i…
The GALAH Survey: Neutron-Capture Elemental Abundances for 350,000 Gaia-RVS Spectra and the Chemodynamics of Accreted Structures
Pradosh Barun Das, Daniel B. Zucker, Aldo Mura-Guzmán +16
We present a comprehensive data-driven spectroscopic analysis of 357,415 red giant stars using Gaia DR3 Radial Velocity Spectrometer (RVS) spectra (8460-8700 A; ),…
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…
Starkiller: subtracting stars and other sources from IFU spectroscopic data through forward modeling
Ryan Ridden-Harper, Michele T. Bannister, Sophie E. Deam +1
We present starkiller, an open-source Python package for forward-modeling flux retrieval from integral field unit spectrograph (IFU) datacubes. Starkiller simultaneously provides s…
