Investigation of a sample of carbon-enhanced metal-poor stars observed with FORS and GMOS
(EDP Sciences, 2018-06)
Aims. 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 investigation within the stellar ...
TOPoS: IV. Chemical abundances from high-resolution observations of seven extremely metal-poor stars
(EDP Sciences, 2018-04)
Context. Extremely metal-poor (EMP) 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 and to provide a chemical ...
