Feedback from massive stars and gas expulsion from proto-Globular Clusters
F. Calura, C. G. Few, D. Romano +1
Globular clusters are considerably more complex structures than previously thought, harbouring at least two stellar generations which present clearly distinct chemical abundances.…
Carbon and nitrogen abundances of individual stars in the Sculptor dwarf spheroidal galaxy
C. Lardo, G. Battaglia, E. Pancino +7
We present [C/Fe] and [N/Fe] abundance ratios and CH(λ4300) and S(λ3883) index measurements for 94 red giant branch (RGB) stars in the Sculptor dwarf spheroidal galaxy from VLT/VIM…
Chemical abundances and properties of the ionized gas in NGC 1705
F. Annibali, M. Tosi, A. Pasquali +3
We obtained [O III] narrow-band imaging and multi-slit MXU spectroscopy of the blue compact dwarf (BCD) galaxy NGC 1705 with FORS2@VLT to derive chemical abundances of PNe and H II…
The role of neutron star mergers in the chemical evolution of the Galactic halo
G. Cescutti, D. Romano, F. Matteucci +2
Aims. We explore the problem of the site of production of Eu. We use also the information present in the observed spread in the Eu abundances in the early Galaxy, not only its aver…
