Abstract:
Photographic spectra of AR Aur, the spectroscopic double-lined (SB2) binary
with chemically peculiar components, were disentangled using the KOREL code and
abundances of chosen chemical elements were determined by means of spectrum
synthesis. In the A - component, for T_eff = 10 950 K and log g = 4.33, Mn, Zr,
Ba, Pt and Hg were found overabundant by factors of 12, 21, 13, 1350 and
2.2 exp 6, respectively. In the B - component, for T_eff = 10 350 K and
log g = 4.20, Mn, Ba and Pt were found overabundant by factors of 5, 170 and
300, respectively. The overabundances derived differ from the previous ones,
except for Mn in the B - component.
