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…
