Primordial Lithium and Big Bang Nucleosynthesis

Ryan, Sean G; Beers, Timothy C; Olive, Keith; Fields, Brian; Norris, John

Description

Recent determinations of the abundance of the light-element Li in very metal-poor stars show that its intrinsic dispersion is essentially zero and that the random error in the estimated mean Li abundance is negligible. However, a decreasing trend in the Li abundance toward lower metallicity indicates that the primordial abundance of Li can be inferred only after allowing for nucleosynthesis processes that must have been in operation in the early history of the Galaxy. We show that the observed...[Show more]
