Lithium Isotopic Abundances in Stars
2008The Li isotope ratio, 6Li/7Li, in stars can be determined from the isotopic shift in the Li I 670.8 nm resonance line. Because of the small effect this however requires truly precision spectroscopy: spectral resolving power R ≥ 105 and S/N ≥ 500. In this review we discuss the method and what one can learn from Li isotopic abundances in terms of Big ...

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 addition to the Li abundance determination, a careful determination of the stellar physical parameters (Teff, log g, [Fe/H]) has been performed. For

Lithium in Population II Stars
1992NEW data about dwarfs : a few more metal-poor dwarfs have been observed for lithium at the CAT + CES at La Silla (ESO). These new results, together with a few new measurements in the literature show again a constant lithium abundance, confirming the trend previously found (the plateau).

The Puzzle of Lithium in Evolved Stars
1986The recent reports on the possible presence of lithium-6 in stars (some above the M.S.), (Andersen, Gustafsson and Lambert 1984) has renewed the interest in the hypothesis of spallation reactions in the surfaces of red giants (Canal, Isern and Sanahuja 1980). Indeed no mechanism has been proposed to generate lithium-6 except high energy reactions.
