Chemical abundances of 20 barium stars from the OHP spectra

Guochao Yang, Jingkun Zhao, Yanchun Liang +7

Based on the high resolution and high signal-to-noise spectra, we derived the chemical abundances of 20 elements for 20 barium (Ba-) stars. For the first time, the detailed abundan…

The metal-poor end of the Spite plateau. II. Detailed chemical investigation

A. Matas Pinto, M. Spite, E. Caffau +7

Context. The study of old, metal-poor stars deepens our knowledge on the early stages of the universe. In particular, the study of these stars gives us a valuable insight into the…

Detailed abundances in a sample of very metal poor stars

P. François, S. Wanajo, E. Caffau +6

Unevolved metal poor stars are the witness of the early evolution of the Galaxy. The determination of their detailed chemical composition is an important tool to understand the che…

Chemical analysis of very metal-poor turn-off stars from SDSS-DR12

P. François, E. Caffau, S. Wanajo +7

The most metal-poor stars are the relics of the early chemical evolution of the Galaxy. Their chemical composition is an important tool to constrain the nucleosynthesis in the firs…

Gaia confirms that SDSS J102915+172927 is a dwarf star

P. Bonifacio, E. Caffau, M. Spite +10

The Gaia Data Release 2 provides a parallax of 0.734+/-0.073 mas for SDSS J102915+172927, currently the most metal-poor known object. This parallax implies that it is dwarf star, r…

Abundance patterns of the light neutron-capture elements in very and extremely metal-poor stars

François Spite, Monique Spite, Beatriz Barbuy +3

We measured new abundances of so-called light neutron-capture of first peak elements using local thermodynamic equilibrium (LTE) 1D analysis; this analysis resulted in a sample of…
