Scientific paper

The wavelength coincidence statistics (WCS) method is used to examine the high-dispersion spectra of a sample of superficially normal late B and early A stars selected on the basis of low projected rotational velocities. Two lists of about 70 strong and weak Fe II lines were used, and line intensities predicted for 10,000 K. On the basis of WCS for stars having published fine analyses, it is suggested that several stars in the sample are deficient in iron and may have sharper-lined spectra than the weak-lined A or Lambda Bootis stars previously recognized. It is further suggested that weak-lined stars, which may represent a large fraction of the late B and early A stars, may have a part of their peculiar chemistry arising from small abundance fluctuations in the interstellar medium.
