[112.25] Continuing Results from the Michigan Catalogue of MK Types for the HD Stars (-90o to +5o)

S.M. Caballero-Nieves, N. Houk (University of Michigan), J.R. Sowell (Georgia Tech)

The Henry Draper Catalogue stars are being systematically reclassified visually by Houk, using 10o objective-prism plates (approximately 108 Å/mm, resolution 2 Å) taken at either Cerro Tololo Inter-American Observatory with the Michigan Curtis Schmidt telescope or at Kitt Peak National Observatory with the Burrell Schmidt telescope. Using the over 160,000 stars now classified, Aitoff Equal Area Projection Plots in galactic coordinates l and b are shown for stars of various spectral types and luminosities, with special emphasis on the supergiants and on peculiar stars, such as the Ap, Am, C, S, WR, Ba, CN, and weak-lined stars.
