Scientific paper

As part of our continuing search for peculiar A-type stars, including λ Boötis stars, in open clusters of all ages, we have obtained classification spectra of nearly 70 late B, A and early F-type stars in 11 young and intermediate-age open clusters, including NGCs 1039, 6633, 7039, 7063, 7092, 7209, 7243, IC 1396, IC 4665, IC 4756 and Stock 2. The spectra were obtained with a resolution of 3.6 Angstroms (2 pixels) on the Dark Sky Observatory 0.8m telescope of Appalachian State University, and were classified on the MK System. Numerous classical Ap and Am stars were found among the 70, along with a few emission-line stars.
