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…

Nitrogen Abundances in High-z DLAs

P. Molaro, M. Centurion, V. D'Odorico +1

Determination of chemical abundances for elements produced mainly by Type I SNae and intermediate mass stars in high redshift DLAs probes the early chemical build-up on time-scales…

Elemental abundances of metal poor carbon rich lead star: CS29497-030

T. Sivarani, P. Bonifacio, P. Molaro +12

We present here the abundance analysis of a metal poor carbon rich lead star, CS29497-030. High resolution and high signal to noise spectra were obtained using the UVES spectrograp…

Chemical Abundances in High-Redshift Neutral Clouds

Paolo Molaro

Neutral hydrogen clouds with high column density detected towards distant quasars are unique probes of elemental nucleosynthesis and chemical evolution in the low metallicity regim…

First UVES observations of beryllium in very metal-poor stars

Francesca Primas, Paolo Molaro, Piercarlo Bonifacio +1

We report on a attempt to detect beryllium in two dwarf stars of the Galactic halo with metallicities below one thousandth solar. The data were obtained during the Commissioning of…

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…
