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.

17 Com B的表面丰度:自洽进化模型的检验

元素丰度是针对16个元素的17 Com B得出的。他们加强了这颗星的上午状态。我们表明,通过恒星模型(包括原子扩散和参数化湍流扩散系数)正确再现了测得的丰度。该参数化与以前的Am星研究中使用的参数一致。
