Abundances and Evolution of Lithium in the Galactic Halo and Disk
Sean G. Ryan, Toshitaka Kajino, Timothy C. Beers +4
We have measured the Li abundance of 18 stars with -2 <~ [Fe/H] ~< -1 and 6000 K <~ Teff <~ 6400 K, a parameter range that was poorly represented in previous studies. We examine th…
A New Model for the Evolution of Light Elements in an Inhomogeneous Galactic Halo
Takeru Ken Suzuki, Yuzuru Yoshii
We present predictions of the evolution of the light elements, Li, Be, and B, in the early epochs of the Galactic halo, using a model of supernova-induced chemical evolution based…
Primordial Lithium Abundance as a Stringent Constraint on the Baryonic Content of the Universe
Takeru Ken Suzuki, Yuzuru Yoshii, Timothy C. Beers
We have refined the estimate of the primordial level of Li abundance to an accuracy better than 10%, based on high-precision Li abundances for metal-poor halo stars, and a rece…
The Light Elements Be and B as Stellar Chronometers in the Early Galaxy
Timothy C. Beers, Takeru K. Suzuki, Yuzuru Yoshii
Recent detailed simulations of Galactic Chemical Evolution have shown that the heavy elements, in particular [Fe/H], are expected to exhibit a weak, or absent, correlation with ste…
