Cosmic Star Formation, Reionization, and Constraints on Global Chemical Evolution
Frederic Daigne, Keith A. Olive, Elisabeth Vangioni-Flam +2
Motivated by the WMAP results indicating an early epoch of reionization, we consider alternative cosmic star formation models which are capable of reionizing the early intergalacti…
Lithium-Beryllium-Boron : Origin and Evolution
Elisabeth Vangioni-Flam, Michel Casse, Jean Audouze
The origin and evolution of Lithium-Beryllium-Boron is a crossing point between different astrophysical fields : optical and gamma spectroscopy, non thermal nucleosynthesis, Big Ba…
New high S/N observations of the Li-6/Li-7 blend in HD 84937 and two other metal-poor stars
R. Cayrel, M. Spite, F. Spite +3
High S/N ratio spectra have been obtained at CFHT at a spectral resolution of 100 000 for HD 84397 and two other metal poor stars. For HD 84 937, the S/N of 650 per pixel was obtai…
Lithium-6 : Evolution from Big Bang to Present
Elisabeth Vangioni-Flam, Michel Casse, Roger Cayrel +3
The primordial abundances of Deuterium, he4, and li7 are crucial to determination of the baryon density of the Universe in the framework of standard Big Bang nucleosynthesis (BBN).…
Star Formation Histories versus Redshift : Consequences for Overall Metallicity and Deuterium Destruction
Michel Casse, Keith A. Olive, Elisabeth Vangioni-Flam +1
The flood of new data on deep surveys, and above all the CFRS (Canada-France-Redshift-Survey), has had a great impact on studies of galactic evolution. On the basis of cosmological…
The first generation of stars: first steps towards chemical evolution of galaxies
Jean Audouze, Joseph Silk
We argue that extreme metal-poor stars show a high dispersion in metallicity, because their abundances are the outcome of very few supernova events. Abundance anomalies should appe…
