Sulphur abundances in disk stars: A correlation with silicon.

CHEN Y.Q., NISSEN P.E., ZHAO G. and ASPLUND M.

Abstract (from CDS):

We have performed new determinations of sulphur and silicon abundances for a sample of 26 disk stars based on high-resolution, high signal-to-noise spectra. The results indicate a solar [S/Fe] for [Fe/H]>-0.3, below which [S/Fe] increases to ∼0.25dex at [Fe/H]=-1.0. We find that there is a good correlation between [S/H] and [Si/H], indicating the same nucleosynthetic origin of the two elements. It seems that the ratio of sulphur to silicon does not depend on metallicity for [Fe/H]>-1.0. The implications of these results on models for the nucleosynthesis of α-capture elements and the chemical evolution of the Galaxy are discussed.
