Abstract
ABSTRACT A survey technique for indicating the potential existence of abundance anomalies in stars with many thousands of lines has been developed using wavelength-coincident-statistics and automated spectrum-line position measuring. The technique has been tested against estimates of Fe abundances in the F stars. It was applied to a group of F stars to search for the possible anomalies in abundance in various metal and rare-earth species that would indicate an extension into the F stars of the CP phenomenon that is commonly observed in the A and B stars. A tentative conclusion is drawn that the evolved star 41 Cyg and the main-sequence star 17 Psc might show rare-earth excesses, with those in 41 Cyg being substantial. Furthermore, the main-sequence stars 12 And and HR 7756 may exhibit rare-earth deficiencies.
