The Diffuse Ionized Interstellar Medium: Structures Resulting from Ionization by O Stars Abstract image available at:http://adsabs.harvard.edu/cgi-bin/nph-bib_query?1993ApJ...417..579M&db_key=AST
New spectral classifications for O-type stars in the Northern Hemisphere In order to update the classifications of O and B stars in the vicinityof the sun, moderate-resolution spectra have been obtained in thewavelength region about 4000 A to about 5000 A of 32 O and B starswithout published luminosity classifications. Normalized spectra andrevised spectral classifications are presented. Two of the stars arefound to be members of the O3 spectral class.
