10516 The region around H gamma is heavily veiled. The luminosity class was 10516 determined from the weakness of lambda 4121. 11415 Shell star. Hydrogen lines are narrow and intense; helium lines are 11415 also narrow. 24534 The region between H beta and H gamma is veiled. He I lambda 4471 is 24534 absent. 26326 Photometry from Hogg (1958). 34959 Shell star. Hydrogen lines are sharp but somewhat veiled; helium lines 34959 are diffuse. 37021 Photometry from Sharpless (1952). 37022 Nebular emission lines are present redward of H beta. 37041 See note to HD 37022. 37202 Shell star. Hydrogen lines are strong and sharp; helium lines are broad. 37479 Helium lines are exceptionally strong. 37971 Shell star. Both hydrogen and helium lines are sharp. Mg II lambda 4481 37971 is rather strong for B3 IV. 60325 He I lambda 4009 is weak and diffuse. Spectrum is otherwise normal for 60325 B2 III. 109387 Hydrogen lines are somewhat diffuse for B6 III. 142983 Shell star. A metallic spectrum is present in addition to the sharp 142983 hydrogen lines and diffuse helium lines. 145502 Hydrogen lines are strong and lambda 4009 is weak for B2 IV. 156633 Hydrogen lines are strong and shaded to the violet. He I lambda 4121 is 156633 somewhat weak for B1.5 V. 170740 Photometry from Johnson (1960). 174179 Shell star. Hydrogen lines are somewhat narrow but otherwise normal. 176304 Spectral type derived from hydrogen and helium lines, but lines of Si II, 176304 Mg II, and O II are all strong. 181858 Hydrogen lines are unusually strong, especially H epsilon and H zeta. 185507 Double-lined spectrscopic binary. Both components are visible in the 185507 hydrogen and helium lines. 193237 Almost all the lines in the spectrum haved redward-displaced emission 193237 components. N II lambda 3995 is unusually strong. 201733 Shell star. Hydrogen lines are sharp, but helium lines are diffuse. 205637 See note to HD 201733. 214167 Photometry from Harris (1955). 217050 A Be star with shell characteristics. H beta is barely reversed, and the 217050 Fe II emission lines are present. The other hydrogen lines are strong 217050 and sharp, while the helium lines are broad. 217543 Shell star. Hydrogen lines are slightly narrow and veiled; helium lines 217543 are very diffuse.
