J/ApJ/300/779       High-latitude H-alpha emission stars     (Stephenson+, 1986)

New H-alpha emission stars found above 10° galactic latitude. Stephenson C.B. <Astrophys. J. 300, 779 (1986)> =1986ApJ...300..779S
ADC_Keywords: Stars, emission ; Surveys Keywords: stars: emission-line Abstract: Approximately 1300 5.2x5.2deg2 red-sensitive objective prism plates have been searched for Hα-emission stars in order to complete the search of the entire sky. The survey here reported represents 59% of the whole sky, defined by the region north of declination -25° and mostly further than 10° from the Galactic plane; the omitted portions had already been surveyed, in part at Warner and Swasey, in part elsewhere. Two hundred and six stars have been newly found, mostly of unknown spectral type. The stars' latitude distribution suggest that they are mainly moderately high luminosity disk population stars. There are new finds especially in Orion and the Taurus dark clouds (limiting mag ∼13). File Summary:

Note (1): Stephenson's magnitudes are systematically too faint by a full magnitude; it also seems that the magnitude is closer to B than to V. Note (2): the spectral type includes information about the strength of the Hα emission: vst = very string; st = string; wk = weak; r = atypically red.
