TOPoS V: Abundance ratios in a sample of very metal-poor turn-off stars
P. François, E. Caffau, P. Bonifacio +12
Extremely metal-poor stars are keys to understand the early evolution of our Galaxy. The ESO large programme TOPoS has been tailored to analyse a new set of metal-poor turn-off sta…
Chemical analysis of very metal-poor turn-off stars from SDSS-DR12
P. François, E. Caffau, S. Wanajo +7
The most metal-poor stars are the relics of the early chemical evolution of the Galaxy. Their chemical composition is an important tool to constrain the nucleosynthesis in the firs…
Investigation of a sample of carbon-enhanced metal-poor stars observed with FORS and GMOS
E. Caffau, A. J. Gallagher, P. Bonifacio +5
Carbon-enhanced metal-poor (CEMP) stars represent a sizeable fraction of all known metal-poor stars in the Galaxy. Their formation and composition remains a significant topic of in…
Using the CIFIST grid of CO5BOLD 3D model atmospheres to study the effects of stellar granulation on photometric colours. II. The role of convection accross the H-R diagram
A. Kučinskas, J. Klevas, H. -G. Ludwig +3
We studied the influence of convection on the spectral energy distributions, photometric magnitudes, and colour indices of different types of stars across the H-R diagram. The 3D h…
TOPoS: IV. Chemical abundances from high-resolution observations of seven EMP stars
P. Bonifacio, E. Caffau, M. Spite +15
Extremely metal-poor stars provide us with indirect information on the first generations of massive stars. The TOPoS survey has been designed to increase the census of these stars…
