The Infrared Ca II triplet as metallicity indicator
Ricardo Carrera, Carme Gallart, Elena Pancino +1
From observations of almost 500 RGB stars in 29 Galactic open and globular clusters, we have investigated the behaviour of the infrared Ca II triplet (8498, 8542 and 8662 Å) in the…
The Rotation of Sub-Populations in omega Centauri
E. Pancino, A. Galfo, F. R. Ferraro +1
We present the first result of the Ital-FLAMES survey of red giant branch (RGB) stars in omega Cen. Radial velocities with a precision of ~0.5 km/s are presented for 650 members of…
Contrasting copper evolution in Omega Centauri and the Milky Way
Donatella Romano, Francesca Matteucci
Despite the many studies on stellar nucleosynthesis published so far, the scenario for the production of Cu in stars remains elusive. In particular, it is still debated whether cop…
Connecting the primordial and Galactic deuterium abundances
Gary Steigman, Donatella Romano, Monica Tosi
The deuterium abundances inferred from observations of the interstellar medium within 1-2 kpc of the Sun range over a factor of three and the corresponding oxygen abundances show a…
3D Simulations of the ISM pollution by SNII and SNI in dwarf spheroidal galaxies
Andrea Marcolini, Fabrizio Brighenti, Annibale D'Ercole +1
We present preliminary results of 3-D hydro simulations of the interstellar medium evolution in dwarf spheroidal galaxies undergoing star formation for the first time. The star for…
Quantifying the uncertainties of chemical evolution studies. I. The stellar initial mass function and the stellar lifetimes
Donatella Romano, Cristina Chiappini, Francesca Matteucci +1
The stellar initial mass function and the stellar lifetimes are basic ingredients of chemical evolution models, for which different recipes can be found in the literature. In this…
