AbstractWe examine the sharp-lined stars HR 6455 (A3 III, v sin i = 8.7 km s -1) and η Lep (F2 V, v sin i = 13.5 km s -1) as well as δ Aqr (A3 V, v sin i = 81 km s -1) and 1 Boo (A1 V, v sin i = 59 km s -1) to increase the number consistently analyzed A and F stars using high dispersion and high S/N (≥200) spectrograms obtained with CCD detectors at the long Coudé camera of the 1.22-m telescope of the Dominion Astrophysical Observatory. Such studies contribute to understanding systematic abundance differences between normal and non-magnetic main-sequence band chemically peculiar A and early F stars. LTE fine analyses of HR 6455, δ Aqr, and 1 Boo using Kurucz's ATLAS suite programs show the same general elemental abundance trends with differences in the metal richness. Light and iron-peak element abundances are generally solar or overabundant while heavy element and rare earth element abundances are overabundant. HR 6455 is an evolved Am star while δ Aqr and 1 Boo show the phenomenon to different extents. Most derived abundances of η Lep are solar. © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
