s- and r-process elements in two very metal-poor stars
Sean G. Ryan, Wako Aoki, Lisa A. J. Blake +5
New measurements of neutron-capture elements are presented for two very metal-poor stars ([Fe/H] ~ -3). One (LP 625-44) has an s-process signature believed to be due to mass transf…
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…
Ongoing Large Surveys for Metal-Poor Stars in the Galactic Halo
Norbert Christlieb, Timothy C. Beers
We report on two major surveys for metal-poor stars in the galactic halo, the HK survey, and the Hamburg/ESO survey, which have been undertaken in order to provide targets for high…
