High resolution spectroscopy of halo stars in groundbased UV.
Abstract
For the first time an atlas of high spectral resolution (R = 60000) CCD-spectra in the low studied wavelenghth range 3500-5000ÅÅ is presented for 4 stars with values of metallicity -3.0<[Fe/H]<-0.6, temperatures 4750<Te<5900K and surface gravity 1.6<log g<5.0. Based on these spectral data we determined model atmosphere parameters and calculated abundances of 29 chemical elements or their ions.
