The Hamburg/ESO R-process Enhanced Star survey (HERES). I. Project description, and discovery of two stars with strong enhancements of neutron-capture elements
N. Christlieb, T. C. Beers, P. S. Barklem +15
We report on a dedicated effort to identify and study metal-poor stars strongly enhanced in r-process elements ([r/Fe] > 1 dex; hereafter r-II stars), the Hamburg/ESO R-process Enh…
Hierarchical Structure Formation and Chemical Evolution of Galaxies
Y. -Z. Qian, G. J. Wasserburg
We present an analytical and phenomenological model for metal enrichment in halos based on hierarchical structure formation. This model assumes that astration of normal stellar pop…
Abundances In Very Metal Poor Dwarf Stars
Judith G. Cohen, Norbert Christlieb, Andrew McWilliam +7
We discuss the detailed composition of 28 extremely metal-poor dwarfs, 22 of which are from the Hamburg/ESO Survey, based on Keck Echelle spectra. Our sample has a median [Fe/H] of…
