Accuracy of the determination of the abundances in solar type stars
The accuracy of the abundances are of course especially interesting when compared to some variations observed : the problem is to find if these variations are significantly larger than the uncertainties. The a...

Nucleosynthesis in the First Galactic Stars
Our aim is to study the detailed chemical composition of the first galactic stars, which contain an important record of the products of nucleosynthesis in the Big Bang and the earliest stellar generations. Sta...

Lithium in Old Binary Stars
A detailed analysis of high resolution, high signal to noise spectra of twenty metal deficient binaries (−2.9 < [Fe/H] < −0.4) with periods ranging from 220d to 1.8d is presented. For most of the stars, in add...

Observational Status of Lithium in Stars
Some of the new data about lithium abundance in stars are reviewed here. The data, that seem more directly linked with the problem of the primordial nucleosynthesis, are briefly discussed. In order to reach a ...
