New analysis of the two carbon-rich stars CS 22948-27 and CS 29497-34 : binarity and neutron-capture elements
B. Barbuy, M. Spite, F. Spite +4
We have carried out a new determination of abundances in the very metal-poor CH/CN strong stars CS 29497-34 and CS 22948-27, using high-resolution spectra obtained with the HARPS s…
First stars VI - Abundances of C, N, O, Li, and mixing in extremely metal-poor giants. Galactic evolution of the light elements
M. Spite, R. Cayrel, B. Plez +11
We have investigated the poorly-understood origin of nitrogen in the early Galaxy by determining N abundances in 35 extremely metal-poor halo giants (22 stars have [Fe/H]<-3.0) usi…
R-process pattern in the Very-Metal-Poor Halo Star CS31082-001
V. Hill, B. Plez, R. Cayrel +1
The very-metal-poor halo star CS31082-001 was discovered to be very strongly r-process-enhanced during the course of a VLT+UVES high-resolution follow-up of metal-poor stars identi…
Age-metallicity relation and Chemical evolution of the LMC from UVES spectra of Globular Cluster giants
V. Hill, P. François, M. Spite +2
We report on the first high-resolution spectroscopy of 10 giants in LMC Globular Clusters in a wide age range, obtained with the newly commissioned spectrograph UVES at VLT UT2. Th…
First results of UVES at VLT: abundancesin the Sgr dSph
Piercarlo Bonifacio, Vanessa Hill, Paolo Molaro +3
Two giants of the Sagittarius dwarf spheroidal have been observed with the UVES spectrograph on the ESO 8.2m Kueyen telescope, during the commissioning of the instrument. Sgr 139 h…
The lithium isotope ratio in the metal-poor halo star G271-162 from VLT/UVES observations
P. E. Nissen, M. Asplund, V. Hill +1
A high resolution (R = 110.000), very high S/N (>600) spectrum of the metal-poor turnoff star G271-162 has been obtained in connection with the commissioning of UVES at VLT/Kueyen.…
