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.
