III/180        SS(77) Catalogue: new H-alpha em* in Milky Way (Stephenson+ 1977)

New H-alpha Emission Stars in the Milky Way. Stephenson C.B., Sanduleak N. <Astrophys. J. Suppl. Ser. 33, 459 (1977)> =1977ApJS...33..459S
ADC_Keywords: Stars, early-type ; Stars, emission Keywords: stars: early-type - stars: emission-line, Be - stars: spectral classification Abstract: Data on 455 H-α emission stars found in all parts of the Milky Way, virtually all previously unpublished, are tabulated, with newly measured coordinates usually accurate to better than 2". A half-dozen stars appear to have been published previously with erroneous coordinates, or to have been published but omitted from the general catalog by Wackerling (1970MmRAS..73..153W). Included among the new stars are known OB stars of the Luminous Stars in the Northern Milky Way survey, from the Hamburg zones, which were originally searched for Hα emission at slightly lower spectral resolution than we have used. The stars are in general of early spectral type, and are mostly fainter than the limits of the DM catalogs. The objective-prism plates covered the entire Milky Way within about 10deg of the galactic equator, at a spectral dispersion of about 1000Å/mm at H-alpha. Note: This is the catalogue which includes the famous SS 433 object. File Summary:

Note on Sp: Spectral types are almost always estimated from 580A/mm blue-region objective-prism plates or quoted from the literature; an absent type means that the star was too faint for our blue plates. The symbols, other than the most standard ones, mean the following: w = H-alpha emission weak, i.e. barely string enough to detect it reliably. s = H-alpha emission strong le = emission lines seen in the blue spectral region OBl = early-type star spectroscopically somewhat less luminous than OB- (in the terminology of the LS catalogue) ce = Balmer continuum in emission r = reddened continuum ov = classification complicated by a spectral overlap on the blue plate
