Chemical abundances in the galactic halo

As a natural extension to our large disk-star abundance study (Edvardsson et al. 1993, A&A 275, 101), a similar study of about 75 halo stars with metallicities [Fe/H] between -2.2 and -0.8 is approaching completion, Jonsell et al. (2000, in preparation). Abundances of 20 chemical elements have been determined, but since the analysis and discussion of the results is not yet finished we can not present any details here.
