First stars VII. Lithium in extremely metal poor dwarfs
P. Bonifacio, P. Molaro, T. Sivarani +12
Aims. This study aims to determine the level and constancy of the Spite plateau as definitively as possible from homogeneous high-quality VLT-UVES spectra of 19 of the most metal-p…

First stars X. The nature of three unevolved Carbon-Enhanced Metal-Poor stars
T. Sivarani, T. C. Beers, P. Bonifacio +13
From high-resolution VLT/UVES spectra (R~43,000), we determine abundances or upper limits for Li, C, N, O, and other important elements, as well as 12C/13C isotopic ratio for three…

First stars IX -Mixing in extremely metal-poor giants. Variation of the 12C/13C, [Na/Mg] and [Al/Mg] ratios
M. Spite, R. Cayrel, V. Hill +11
Extremely metal-poor (EMP) stars preserve a fossil record of the composition of the ISM when the Galaxy formed. It is crucial, however, to verify whether internal mixing has modifi…
