    [delta] Ceti is not monoperiodic: seismic modeling of a [beta] Cephei star from MOST space-based photometry 
    Guenther, David B.; Aerts, C.; Marchenko, S. V.; Matthews, J. M.; Kuschnig, R.; Moffat, A. F. J.; Rucinski, S. M.; Sasselov, D.; Walker, G. A. H.; Weiss, W. W. (American Astronomical Society, 2006-05)
    The [beta] Cephei star [delta] Ceti was considered one of the few monoperiodic variables in its class. Despite (or perhaps because of) its apparently simple oscillation spectrum, it has been challenging and controversial ...

    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 ...
