[47.08] The Incidence of \lambda Bootis Stars among Pre-Main Sequence A-type Stars

R. O. Gray (Appalachian State University), C. J. Corbally (Vatican Observatory)

We have obtained high S/N CCD MK classification spectra (3.6 Åpixel resolution) of a total of 19 pre-main sequence and ZAMS A-type stars in the young open clusters NGC 2264 and NGC 7160 and of a sample of 27 Ae stars. We report on the spectral types of these stars, and the discovery of \lambda Bootis stars among these young objects.
