First Stars XIV. Sulfur abundances in extremely metal-poor (EMP) stars

Spite, Monique Caffau, E. Andrievsky, S.M.

Sulfur is important: the site of its formation is uncertain, and at very low metallicity the trend of [S/Fe] against [Fe/H] is controversial. Below [Fe/H]=-2.0, [S/Fe] remains constant or it decreases with [Fe/H], depending on the author and the multiplet used in the analysis. Moreover, although sulfur is not significantly bound in dust grains...

Young [α/Fe]-enhanced stars discovered by CoRoT and APOGEE: What is their origin?

Chiappini, C. Anders, F. Rodrigues, T. S.

We report the discovery of a group of apparently young CoRoT red-giant stars exhibiting enhanced [α/Fe] abundance ratios (as determined from APOGEE spectra) with respect to solar values. Their existence is not explained bystandard chemical evolution models of the Milky Way, and shows that the chemical-enrichment history of the Galactic disc is...
