cds-question@unistra.frchemical-abundancesTo obtain detailed silicon abundances of metal-poor stars, we aim to explore the correlation between the abundance ratios and the stellar parameters and the chemical enrichment of the interstellar medium (ISM). We determined the silicon abundances of 253 metal-poor stars in the metallicity range -4<[Fe/H]<-1.5, based on non-local thermodynamic equilibrium (NLTE) line formation calculations of neutral silicon and high-resolution spectra obtained with VLT-UT2/UVES.2011A&A...528A..92Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/528/A92CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/439/129 : HERES II.
