J/AJ/107/1556                 Late B-type stars classification (Garrison+, 1994)

The late B-Type Stars: refined MK classification, confrontation with Stromgren photometry, and the effects of rotation Garrison R.F., Gray R.O. <Astron. J. 107, 1556 (1994)> =1994AJ....107.1556G
ADC_Keywords: MK spectral classification ; Stars, B-type ; Photometry, uvby, beta Abstract: In the fourth and final of a series of papers on the late B to the early F type stars, we refine the MK spectral classification system for the late B type stars and consider the effect of rotation on both spectral classification and Stromgren photometry of these stars. We extend the work of Morgan by establishing self-consistent sequences of narrow and broadlined standards. We reclassify a number of Bp stars, compare these classifications with Stromgren photometry and consider the question of whether all Bp stars are main-sequence objects. File Summary:
