Evidence of Mixing in Extremely Metal-Poor Giants
Thirty five extremely metal-poor (EMP) giants (22 of them with a metallicity [Fe/H] ≤ -3.0) have been observed with UVES at the VLT. In these stars the abundance of lithium carbon and nitrogen and also the 12C/13

Sulphur in the Early Ages of the Galaxy
We present here the results of the measurement of the sulphur abundance in very metal-poor stars. Our sample covers the [-4;-2] range of metallicity, and thus allows us to constraint the chemical evolution mod...

Abundance of Heavy Elements in Extremely Metal-Poor Stars
In the framework of the VLT Large program “First Stars” (165.N-0276(A)), we have measured the abundance of 13 heavy elements using high quality UVES spectra. In this paper, we report on the abundance of Sr and...
