    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 ...

    Massive open star clusters using the VVV survey II. Discovery of six clusters with Wolf-Rayet stars 
    Majaess, Daniel J.; Chene, A.-N.; Borissova, J.; Bonatto, C.; Baume, G.; Clarke, J. R. A.; Kurtev, R.; Schnurr, O.; Bouret, J.-C.; Catelan, M. (EDP Sciences for European Southern Observatory, 2013-01)
    Context. The ESO Public Survey “VISTA Variables in the Vía Láctea” (VVV) provides deep multi-epoch infrared observations for an unprecedented 562 sq. degrees of the Galactic bulge, and adjacent regions of the disk. Nearly ...

    MOST finds no coherent oscillations in the hot carbon-rich Wolf-Rayet star HD 165763 (WR 111) 
    Guenther, David B.; Moffat, A. F. J.; Marchenko, S. V.; Zhilyaev, B. E.; Rowe, J. F.; Muntean, V.; Chene, A.-N.; Matthews, J. M.; Kuschnig, R.; Rucinski, S. M. (American Astronomical SocietyIOP Publishing, 2008-05-20)
    We have photometrically monitored the V = 8 mag Galactic Population I WC5 star WR 111 for 3 weeks nonstop using the MOST microsatellite. Each of the ∼27,000 data points has a precision of ∼3 mmag. We find no coherent Fourier ...

    Oscillations in the massive Wolf-Rayet star WR 123 with the MOST satellite 
    Guenther, David B.; Lefevre, L.; Marchenko, S. V.; Moffat, A. F. J.; Chene, A. N.; Smith, S. R.; St-Louis, N.; Matthews, J. M.; Kuschnig, R.; Poteet, C. A. (American Astronomical Society and IOP Publishing, 2005-11-20)
    We present the results of intensive visual-broadband photometric monitoring of the highly variable WN8 Wolf-Rayet star WR 123, obtained by the MOST (Microvariability and Oscillations of STars) satellite. This first Canadian ...

    Using MOST to reveal the secrets of the mischievous Wolf–Rayet binary CV Ser 
    Guenther, David B.; David-Uraz, Alexandre; Moffat, Anthony F. J.; Chene, Andre-Nicolas; Rowe, Jason F.; Lange, Nicholas; Kuschnig, Rainer; Matthews, Jaymie M.; Rucinski, Slavek M.; Sasselov, Dimitar (Royal Astronomical Society, 2012)
    The Wolf–Rayet (WR) binary CV Serpentis (= WR113, WC8d + O8-9IV) has been a source of mystery since it was shown that its atmospheric eclipses change with time over decades, in addition to its sporadic dust production. The ...

    WR 110: a single Wolf–Rayet star with corotating interaction regions in its wind? 
    Chene, A.-N.; Moffat, A. F .J.; Cameron, Chris; Fahed, R.; Gamen, R. C.; Lefevre, L.; Rowe, J. F.; St.-Louis, N.; Muntean, V.; De La Chevrotiere, A.; Guenther, David B. (American Astronomical Society, 2011-07-01)
    A 30 day contiguous photometric run with the Microvariability and Oscillations of STars (MOST) satellite on the WN5-6b star WR 110 (HD 165688) reveals a fundamental periodicity of P = 4.08 ± 0.55 days along with a number ...

    The young open cluster Stock 16: an example of star formation in an elephant trunk? 
    Turner, David Gerald, 1945- (American Astronomical Society, 1985-05-01)
    UBV photometry is presented for 33 stars in the young open cluster Stock 16 lying in the H II region RCW 75, and these observations are used to obtain new values for the reddening (E[subscript B-V] = 0.49 [plus or minus] ...
