Dynamical and chemical evolution of NGC1569
S. Recchi, G. Hensler, L. Angeretti +1
Blue Compact Dwarf and Dwarf Irregular galaxies are generally believed to be unevolved objects, due to their blue colors, compact appearance and large gas fractions. Many of these…
Sulphur abundance in Galactic stars
E. Caffau, P. Bonifacio, R. Faraggiana +3
We investigate sulphur abundance in 74 Galactic stars by using high resolution spectra obtained at ESO VLT and NTT telescopes. For the first time the abundances are derived, where…
The metal abundance distribution of the oldest stellar component in the Sculptor dwarf spheroidal galaxy
G. Clementini, V. Ripepi, A. Bragaglia +3
(abridged): Low resolution spectroscopy obtained with FORS2 at the Very Large Telescope (VLT) has been used to measure individual metal abundances ([Fe/H]) for 107 RR Lyrae stars,…
A Supernova Factory in Mrk 273?
M. Bondi, M-A. Perez-Torres, D. Dallacasa +1
We report on 1.6 and 5.0 GHz observations of the ultraluminous infrared galaxy (ULIRG) Mrk 273, using the European VLBI Network (EVN) and the Multi-Element Radio-Linked Interferome…
Cryogenic Filters for RFI Mitigation in Radioastronomy
G. Tuccari, A. Caddemi, S. Barbarino +4
RFI mitigation in Radioastronomy can be achieved adopting cryogenic filters in appropriate typologies. A study has been conducted in L, C and X band with the evaluation of the filt…
The s-process weak component: uncertainties due to convective overshooting
Vincenzo Costa, Maria Letizia Pumo, Alfio Bonanno +1
Using a new s-nucleosynthesis code, coupled with the stellar evolution code Star2003, we performed simulations to study the impact of the convection treatment on the s-process duri…
