Chemical Evolution of R-process Elements in Stars (CERES). I. Stellar parameters and chemical abundances from Na to Zr
Linda Lombardo, Piercarlo Bonifacio, Patrick François +10
Aims. The Chemical Evolution of R-process Elements in Stars (CERES) project aims to provide a homogeneous analysis of a sample of metal-poor stars ([Fe/H]<-1.5). We present the ste…
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…
The Gaia -ESO Survey: Lithium enrichment histories of the Galactic thick and thin disc
Xiaoting. Fu, D. Romano, A. Bragaglia +32
Lithium abundance in most of the warm metal-poor main sequence stars shows a constant plateau (A(Li)~2.2 dex) and then the upper envelope of the lithium vs. metallicity distributio…
A new algorithm for optimizing the wavelength coverage for spectroscopic studies: Spectral Wavelength Optimization Code (SWOC)
G. R. Ruchti, S. Feltzing, K. Lind +7
The past decade and a half has seen the design and execution of several ground-based spectroscopic surveys, both Galactic and Extra-galactic. Additionally, new surveys are being de…
The chemical composition of red giants in 47 Tucanae. II. Magnesium isotopes and pollution scenarios
A. O. Thygesen, L. Sbordone, H. -G. Ludwig +6
The phenomenon of multiple populations in globular clusters is still far from understood, with several proposed mechanisms to explain the observed behaviour. The study of elemental…
Stellar science from a blue wavelength range - A possible design for the blue arm of 4MOST
C. J. Hansen, H. -G. Ludwig, W. Seifert +12
From stellar spectra, a variety of physical properties of stars can be derived. In particular, the chemical composition of stellar atmospheres can be inferred from absorption line…
