    The distance to the young open cluster Westerlund 2 
    Carraro, G.; Turner, David Gerald, 1945-; Majaess, Daniel J.; Baume, G. (EDP Sciences, 2013-07)

    A new X-ray, UBVRIc, and JHKs study of the young cluster Westerlund 2 was undertaken to resolve discrepancies tied to the cluster’s distance. Existing spectroscopic observations for ...

    The evolution of very massive stars 
    Bever, J. Van; Belkus, H.; Vanbeveren, D. (American Astronomical Society, 2007-04)
    Core collapse of dense massive star clusters is unavoidable, and this leads to the formation of massive objects, with masses of up to 1000 M[circled dot] and even larger. When these objects become stars, stellar wind mass ...

    MOST detects g- and p-modes in the B supergiant HD 163899 (B2 Ib/II ) 
    Saio, H.; Kuschnig, R.; Gautschy, A.; Cameron, Chris; Walker, G. A. H.; Matthews, J. M.; Guenther, David B.; Moffat, A. F .J.; Rucinski, S. M.; Sasselov, D. (American Astronomical Society, 2006-10-20)
    The Microvariability and Oscillations of Stars (MOST ) satellite observed the B supergiant HD 163899 (B2 Ib/ II ) for 37 days as a guide star and detected 48 frequencies [less than tilde] 2.8 cycles day [superscript minus ...

    New evidence supporting cluster membership for the keystone calibrator Delta Cephei 
    Majaess, Daniel J.; Turner, David Gerald, 1945-; Gieren, W. (IOP Publishing Limited, 2012-03-10)
    New and existing UBVJHKs, spectroscopic, NOMAD, Hubble Space Telescope, and revised Hipparcos observations are employed to determine properties for δ Cep and its host star cluster. The multi-faceted approach ...
