Unveiling the nature of HE 0107-5240
E. Caffau, M. Steffen, P. Molaro +27
The vast majority of the most iron-poor stars in the Galaxy exhibit a strong carbon enhancement, with C/H ratios only about two orders of magnitude below solar. This unusual chemic…
SDSS J102915.14+172927.9: Revisiting the chemical pattern
E. Caffau, P. Bonifacio, L. Monaco +7
Context: The small- to intermediate-mass (), most metal-poor stars that formed in the infancy of the Universe are still shining today in the sky. They are very rare…
MINCE II. Neutron capture elements
P. François, G. Cescutti, P. Bonifacio +24
The MINCE (Measuring at Intermediate metallicity Neutron-Capture Elements) project aims to gather the abundances of neutron-capture elements but also of light elements and iron pea…
TOPoS: III. An ultra iron-poor multiple CEMP system
E. Caffau, P. Bonifacio, M. Spite +15
One of the primary objectives of the TOPoS survey is to search for the most metal-poor stars. Our search has led to the discovery of one of the most iron-poor objects known, SDSS\,…
The photospheric solar oxygen project: II. Non-concordance of the oxygen abundance derived from two forbidden lines
Elisabetta Caffau, Hans-G. Ludwig, Jean-M. Malherbe +3
In the Sun, the two forbidden [OI] lines at 630 and 636 nm were previously found to provide discrepant oxygen abundances. aims: We investigate whether this discrepancy is peculiar…
