Primordial lithium and the standard model(s)., by Deliyannis, C. P.; Demarque, P.; Kawaler, S. D.; Krauss, L. M.; Romanelli, P..

Physics

Scientific paper

The authors present the results of new theoretical work on surface 7Li and 6Li evolution in the oldest halo stars along with a new and refined analysis of the predicted primordial lithium abundance resulting from big-bang nucleosynthesis. This allows to determine the constraints which can be imposed upon cosmology by a consideration of primordial lithium using both standard big-bang and standard stellar evolution models. Such considerations lead to a constraint on the baryon density today of 0.0044 < Ωbh2 < 0.025, and impose limitations on alternative nucleosynthesis scenarios.
