Neutron-Capture Element Trends in the Halo
arXiv:astro-ph/0101439 · doi:10.1142/9789812810830_0041
Abstract
In a brief review of abundances neutron-capture elements (Z > ~30) in metal-poor halo stars, attention is called to their star-to-star scatter, the dominance of r-process synthesis at lowest metallicities, the puzzle of the lighter members of this element group, and the possibility of a better r-/s-process discriminant.
