Journal ArticleDOI
First stars V - abundance patterns from C to Zn and supernova yields in the early galaxy
R. Cayrel,E. Depagne,M. Spite,Vanessa Hill,F. Spite,P. Francois,Bertrand Plez,Timothy C. Beers,Francesca Primas,Johannes Andersen,Beatriz Barbuy,Piercarlo Bonifacio,Paolo Molaro,Birgitta Nordström +13 more
TL;DR: In this paper, the abundance analysis of an homogeneous sample of 35 giants selected from the HK survey of Beers et al. was presented, emphasizing stars of extremely low metallicity: 30 of the 35 stars are in the range −4.1 < (Fe/H) < −2.7, and 22 stars have (Fe /H) ≥ −3.0.
Journal ArticleDOI
First stars. I. The extreme r-element rich, iron-poor halo giant CS 31082-001 - Implications for the r-process site(s) and radioactive cosmochronology
Vanessa Hill,Bertrand Plez,Roger Cayrel,Timothy C. Beers,Birgitta Nordström,Johannes Andersen,M. Spite,F. Spite,Beatriz Barbuy,P. Bonifactio,E. Depagne,P. Francois,Francesca Primas +12 more
TL;DR: In this article, a high-resolution (R = 75 000, S/N 500) spectroscopic analysis of the bright (V = 11.7), extreme halo giant CS 31082-001 ((Fe/H) = 2.9), obtained in an ESO-VLT Large Programme dedicated to very metal-poor stars.

TL;DR: In this paper, Cayrel et al. investigated the origin of nitrogen in the early Galaxy by determining N abundances from the NH band at 336 nm in 35 extremely metal-poor halo giants.
Journal ArticleDOI
