Sulphur and zinc abundances in galactic halo stars revisited

Nissen, Poul E; Akerman, Chris J; Asplund, Martin; Fabbian, Damian; Kerber, Florian; Kaufl, Hans Ulrich; Pettini, Max

Description

Aims. Based on a new set of sulphur abundances in very metal-poor stars and an improved analysis of previous data, we aim at resolving current discrepancies on the trend of S/Fe vs. Fe/H and thereby gain better insight into the nucleosynthesis of sulphur. The trends of Zn/Fe and S/Zn will also be studied. Methods. High resolution VLT/UVES spectra of 40 main-sequence stars with -3.3 < [Fe/H] < -1.0 are used to derive S abundances from the weak λ8694.6 S I line and the stronger λλ9212.9, 9237.5...[Show more]
