Heavy elements abundances in turn-off stars and early subgiants in NGC 6752
G. James, P. Francois, P. Bonifacio +12
High resolution spectra (R > 40 000) for 9 main sequence turn-off stars and 9 subgiants in the globular cluster NGC 6752 were acquired with UVES on the VLT-Kueyen (UT2). These data…
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…
Ar I as a tracer of ionization evolution
Giovanni Vladilo, Miriam Centurion, Valentina D'Odorico +1
We present a study of Ar abundances in 15 damped Ly alpha systems (DLAs) in the redshift interval from 2.3 to 3.4. The sample includes 4 new UVES/VLT measurements of Ar I column de…
Early stages of Nitrogen enrichment in galaxies: Clues from measurements in damped Lyman alpha systems
M. Centurion, P. Molaro, G. Vladilo +3
We present 4 new measurements of nitrogen abundances and one upper limit in damped Lyman alpha absorbers (DLAs) obtained by means of high resolution (FWHM \~ 7 km/s) UVES/VLT spect…
