Elemental abundances in the atmospheres of three metal-deficient giants.

MISHENINA T.V., KLOCHKOVA V.G. and PANCHUK V.E.

Abstract (from CDS):

High dispersion high resolution CCD spectra have been used for the determination of the elemental abundances in three metal-deficient stars. The following results were obtained: 1) an overabundance of O is found; 2) Si, Ca, Ti are overabundant with respect to iron in stars with [Fe/H]= -1.5; 3) halo stars show an underabundance of the odd elements Na and Al relative to the abundance of the even element Mg); 4) Ni and Mn are slightly overdeficient; 5) an underabundance of Cu is found in all three stars ; 6) s-process elements are slightly overabundant.
