The intrinsic dispersion of elemental abundance ratios in nearby metal-poor halo stars
Poul Erik Nissen, Anish Amarsi
Differential abundances of C, O, Mg, Al, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Zn, Y, and Zr were determined from high signal-to-noise VLT/UVES spectra for 25 turnoff stars with -2.4…
3D NLTE Sodium abundances in late-type stars. Abundance corrections and synthetic spectra
G. Canocchi, E. X. Wang, A. M. Amarsi +2
Neutral sodium is an important tracer of the Galactic chemical evolution, a powerful diagnostic of different stellar populations, and the subject of detailed studies of exoplanet a…
Molybdenum and ruthenium in the Galactic disk: A closer look at their nucleosynthesis components
Tamara Mishenina, Teresa Kurtukian-Nieto, Tatiana Gorbaneva +3
The stellar origin of the elements molybdenum (Mo, Z=42) and ruthenium (Ru, Z=44) is still a matter of debate. Studying their abundances provides valuable insights into nucleosynth…
Abundance Analysis of Chemically Depleted Post-AGB/Post-RGB Binaries with Faint Discs
Maksym Mohorian, Devika Kamath, Meghna Menon +4
Post-AGB and post-RGB binaries with stable circumbinary discs provide key insights into late stellar and disc evolution, revealing how binary interactions shape disc structure and…
s-process Enriched Post-AGB Star J003643.94-723722.1 in the SMC with an Extreme C/O Ratio and the First Precise Detection of Lead
Meghna Menon, Devika Kamath, Maksym Mohorian +6
Post-asymptotic giant branch (post-AGB) stars are exquisite tracers of s-process nucleosynthesis via their surface abundances. We present a comprehensive analysis of J003643.947…
How homogeneous was the chemical enrichment of the Milky Way 13 gigayears ago?
Riano E. Giribaldi, Laura Magrini, Martina Rossi +3
We reanalyze the chemical composition of the metal-poorest tail of the Galactic halo using highly accurate atmospheric parameters Giribaldi et al. (2021, 2023) and cutting-edge 3D…
