The Surface Abundances of 17 Com B: A Test for Self-consistent Evolutionary Models.

DEAL M. and MONIER R.

Abstract (from CDS):

Elemental abundances are derived for 17 Com B for 16 elements. They reinforce the Am status of this star. We show that the measured abundances are properly reproduced by stellar models including atomic diffusion and a parametrized turbulent diffusion coefficient. This parameterization agrees with that used in previous studies of Am stars.
