CDROM/AJ/V107/P1556 Late B Type Stars (Garrison & Gray 1994) ================================================================================ The Late B-Type Stars: Refined MK Classification, Confrontation with Stromgren Photometry, and the Effects of Rotation R. F. Garrison & R. O. Gray <1994, AJ, 107, 1556> =1994AJ....107.1556G ================================================================================ 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.
