Abstract:
Abundances of Mg, Ca, Sc, Cr, Fe, and Ni are derived for A stars of five
nearby open clusters of various ages using high resolution spectroscopy.
We point out a correlation between the abundance of Ca and that of Sc,
suggesting that the abundance anomalies of these elements arise from
the same physical process. Pronounced Am patterns are rather found in
the oldest cluster stars whereas younger targets show weaker Am anomalies
and atypical patterns for some of them.
