Abstract

Abundances of Fe, Ti, Cr, Mg and He have been determined for 10 stars: 5 B, 3A, 1 F dwarfs and 1 chemically peculiar giant B8IIIp with apparentvelocities ranging from 15 to 130 km s-1, members of the Alpha Persei open cluster (log age = 7.40 yrs). The method consists in adjusting grids of synthetic spectra calculated with SYNSPEC48 (Hubeny & Lanz 1992) in the wavelength range of4450–4600 Å. The input model atmospheres are LTE, RE, plane parallel lineblanketed models calculated with ATLAS9 (Kurucz 1992a). A correlation may existbetween [Fe/H] and the effective temperature. Further observations of a much larger sample of B, A and F stars in this cluster areforeseen in the near future.
