Fig. 1


Example of the quality of the spectra of the stars in our sample. A complete line identification of this spectral interval has been performed using the VALD database (Kupka et al. 1999). Elements with atomic number Z smaller than 30 are indicated with a full line, light s-process elements with a dashed line, and heavy s-process elements with a dotted line. As the lower spectrum differs significantly from the upper four, other features are indicated on it. All objects are clearly enhanced in s-process elements, although this is less obvious in the spectrum of J050632 due to its higher temperature.
