Origin of Anomalous Xe-H in Nanodiamond Stardust
K. -L. Kratz, K. Farouqi, O. Hallmann +2
Still today, the nucleosynthesis origin of Xe-H in presolar nanodiamonds is far from understood. Historically, possible explanations were proposed by a secondary "neutron-burst" pr…
The Ubiquity of the Rapid Neutron-Capture Process
I. U. Roederer, J. J. Cowan, A. I. Karakas +5
To better characterize the abundance patterns produced by the r-process, we have derived new abundances or upper limits for the heavy elements zinc (Zn), yttrium (Y), lanthanum (La…
The Hamburg/ESO R-process Enhanced Star survey (HERES) IV. Detailed abundance analysis and age dating of the strongly r-process enhanced stars CS 29491-069 and HE 1219-0312
W. Hayek, U. Wiesendahl, N. Christlieb +8
We report on a detailed abundance analysis of two strongly r-process enhanced, very metal-poor stars newly discovered in the HERES project, CS 29491-069 ([Fe/H]=-2.51, [r/Fe]=+1.1)…
Co-production of light p-, s- and r-process isotopes in the high-entropy wind of type II supernovae
K. Farouqi, K. -L. Kratz, B. Pfeiffer
We have performed large-scale nucleosynthesis calculations within the high-entropy-wind (HEW) scenario of type II supernovae. The primary aim was to constrain the conditions for th…
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…
