    Effects of rotation on stellar spectra 
    Gillich, Aaron (Halifax, N.S. : Saint Mary's University, 2007)
    Models have been produced to study the spectral energy distributions (SEDs) and absorption lines for rapidly rotating B stars. A fully implicit 2D stellar structure and evolution code was used to generate the rotating ...

    HR 5907: discovery of the most rapidly rotating magnetic early B-type star by the MiMeS collaboration 
    Guenther, David B.; Grunhut, J. H.; Rivinius, Th.; Wade, G. A.; Townsend, R. H. D.; Marcolino, W. L. F.; Bohlender, D. A.; Szeifert, Th.; Petit, V.; Matthews, J. M. (Oxford University Press, 2012-01)
    We report the discovery and analysis of a very strong magnetic field in the rapidly rotating early B-type star HR 5907, based on observations obtained as part of the Magnetism in Massive Stars (MiMeS) project. We infer a ...

    Models of Achernar : evolution and atmospheres of a rapidly rotating B star 
    Lovekin, Catherine (Halifax, N.S. : Saint Mary's University, 2005)
    I investigate the effects of varying internal angular momentum distributions on the SEDs of massive stars. Rapidly rotating stars are deformed by rotation, and the degree of deformation can give us a further constraint on ...

    New slowly pulsating B stars in the field of the young open cluster NGC 2244 discovered by the MOST photometric satellite 
    Guenther, David B.; Gruber, D.; Saio, H.; Kuschnig, R.; Fossati, L.; Handler, G.; Zwintz, K.; Weiss, W. W.; Matthews, J. M.; Moffat, A. F. J. (Oxford University Press, 2012-02)
    During two weeks of nearly continuous optical photometry of the young open cluster NGC 2244 obtained by the Microvariability and Oscillations of STars (MOST) satellite,we discovered two new slowly pulsating B (SPB) stars, ...

    A search for OB associations near southern long-period Cepheids. V. AQ Puppis and V620 Puppis 
    Turner, David Gerald, 1945-; van den Bergh, S.; Younger, P. F.; Majaess, Daniel J.; Pedreros, M. H.; Berdnikov, L. N. (IOP Publishing Limited, 2012-12)
    A photometric UBV survey is presented for 610 stars in a region surrounding the Cepheid AQ Puppis and centered southwest of the variable, based upon photoelectric measures for 14 stars and calibrated iris photometry of ...
