VizieR Online Data Catalog: s-process abundances in halo stars (Guiglion+, 2024)
Abstract
Thanks to high resolution spectra from Ruchti et al. (2011ApJ...743..107R) and high quality LTE and NLTE atmospheric parameters from Ruchti et al. (2013MNRAS.429..126R, Cat. J/MNRAS/429/126), we dervied chemical abundances of Y, Sr, and Ba for 323 stars, using an automatic spectral fitting method.
We provide the star identifier, [Fe/H], [Sr/Fe], [Y/Fe], and [Ba/Fe] in LTE and NLTE and associated errors. We also provide individual line abundances. (1 data file).- Publication:
