J/ApJ/105/85        A search for faint blue stars            (Humason+, 1947)

A search for faint blue stars. Humason M.L., Zwicky F. <Astrophys. J., 105, 85-91 (1947)> =1947ApJ...105...85H
ADC_Keywords: Stars, blue Description: Four-color photography has been used in a search for faint blue stars with the 18-inch Schmidt telescope at Palomar, undertaken in the hope of finding new white dwarfs. The results are given for stars brighter than magnitude 15.0pg in 2 regions: the Hyades cluster and the North Galactic Pole. Spectroscopic observations were made with the 100-inch reflector. In the "hz.dat" file, corresponding to the table 4 of the paper, the stars were identified and accurate positions added by B. Skiff (Lowell Observatory) in January 2005, using the finding charts published in the "First Conference on Faint Blue Stars" held in Strasbourg in Aug. 1964, p.121 (Univ. Minnesota, 1965) File Summary:
