The main goal of this project is to gather all the relevant information concerning the Milky Way Halo and, through the analysis of available databases in the literature and the observation of pre-selected objects, contribute to the understanding of this peculiar Galactic component. Over the last few years, surveys such as the SDSS (Sloan Digital Sky Survey), increased the number of stella…
It has been recognized that a large fraction, in excess of 20%, of stars with metallicities [Fe/H]<-2.0, exhibit large overabundances of carbon, [C/Fe]>+1.0. This fraction rises to 30% for [Fe/H]<-3.0, 40% for [Fe/H]<-3.5, and100% for [Fe/H]<-4.0. The vast majority of such stars were identified from objective-prism surveys, such as the HK survey of Beers and colleagues, and the Hamburg/E…
"Snapshot" spectra of high resolution for a sample of ~ 500 targets with [Fe/H] < -2.0 selected from HK and HEs surveys are being obtained with UVES/VLT, as part of the HERES survey (Hamburg/ESO R-process Enhanced Star). The resolving power (R=20000) and the S/N (~ 30/1) requirements are sufficient to allow confident identification of the presence (or absence) of the Eu II 4129A line in …
This proposal seeks to discover (and re-discover) metal-poor stars in the Galaxy, by means of spectroscopic analysis, ranging from low- to high-resolution observations. These discoveries will be made by continuing the efforts started in 2007, which selected a sample of thousands of carbon-enhanced metal-poor star candidates, based on their low-resolution spectra from objective-prism plate…
