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…
High speed stars: III. Detailed abundances and binary nature of the extreme speed star GHS143
E. Caffau, P. Bonifacio L. Monaco, L. Sbordone +7
The Gaia satellite has provided the community with three releases containing astrometrical and photometric data as well as by products, such as stellar parameters and variability i…
The Gaia-ESO Survey: Lithium measurements and new curves of growth
E. Franciosini, S. Randich, P. de Laverny +37
The Gaia-ESO Survey (GES) is a large public spectroscopic survey that was carried out using the multi-object FLAMES spectrograph at the Very Large Telescope. The survey provides ac…
Young giants of intermediate mass Evidence of rotation and mixing
Linda Lombardo, Patrick François, Piercarlo Bonifacio +7
In the search of a sample of metal-poor bright giants using Str{ö}mgren photometry, we serendipitously found a sample of 26 young (ages younger than 1 Gyr) metal-rich giants, some…
Barium lines in high-quality spectra of two metal-poor giants in the Galactic halo
G. Cescutti, C. Morossi, M. Franchini +9
Context. Theoretical results showed the possibility that neutron capture elements were produced in the early Universe by two different sources: a frequent s-process source hosted b…
Does the chemical signature of TYC 8442-1036-1 originate from a rotating massive star that died in a faint explosion?
G. Cescutti, M. Valentini, P. François +4
Context. We have recently investigated the origin of chemical signatures observed in Galactic halo stars by means of a stochastic chemical evolution model. We have found that rotat…
