Lithium abundance in a turnoff halo star on an extreme orbit
Monique Spite, François Spite, Elisabetta Caffau +1
The lithium abundance in turnoff stars of the old population of our Galaxy is remarkably constant in the metallicity interval -2.8\textless{}[Fe/H] \textless{}-2.0, defining a plat…
Grid of theoretical NLTE equivalent widths of four Ba II lines and barium abundance in cool stars
S. A. Korotin, S. M. Andrievsky, C. J. Hansen +5
We present a grid of computed non-local thermodynamic equilibrium (NLTE) equivalent widths (EW) and NLTE abundance corrections for four Ba II lines: 4554, 5853, 6141, and 6496 A. T…
TOPoS: II. On the bimodality of carbon abundance in CEMP stars. Implications on the early chemical evolution of galaxies
P. Bonifacio, E. Caffau, M. Spite +18
In the course of the TOPoS (Turn Off Primordial Stars) survey, aimed at discovering the lowest metallicity stars, we have found several carbon-enhanced metal-poor (CEMP) stars. We…
