    Insights into the inner regions of the FU Orionis disc 
    Siwak, Michal; Winiarski, Maciej; Ogłoza, Waldemar; Dróżdż, Marek; Zola, Stanisław; Moffat, Anthony; Stachowski, Grzegorz; Rucinski, Slavek M.; Cameron, Chris; Guenther, David B. (EDP Sciences, 2018-10)
    Context. We investigate small-amplitude light variations in FU Ori occurring in timescales of days and weeks. Aims. We seek to determine the mechanisms that lead to these light changes. Methods. The visual light curve of ...

    Looking for giant earths in the HD 209458 system: a search for transits in MOST space-based photometry 
    Guenther, David B.; Croll, Bryce; Matthews, Jaymie M.; Rowe, Jason F.; Kuschnig, Rainer; Walker, Andrew; Gladman, Brett; Sasselov, Dimitar; Cameron, Chris; Walker, Gordon A. H. (American Astronomical Society, 2007-04)
    We have made a comprehensive transit search for exoplanets down to about 2 Earth radii in the HD 209458 system, based on nearly uninterrupted broadband optical photometry obtained with the MOST (Microvariability and ...

    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 ...

    MOST detects SPBe pulsations in HD 127756 and HD 217543: asteroseismic rotation rates independent of v sin i[superscript 1] 
    Guenther, David B.; Cameron, Chris; Saio, H.; Kuschnig, R.; Walker, G. A. H.; Matthews, J. M.; Moffat, A. F. J.; Rucinski, S. M.; Sasselov, D.; Weiss, W. W. (American Astronomical Society, 2008-09)
    The MOST (Microvariability and Oscillations of Stars ) satellite has discovered SPBe (slowly pulsating Be) oscillations in the stars HD 127756 (B1/B2 Vne) and HD 217543 (B3 Vpe). For HD 127756, 30 significant frequencies ...

    MOST detects transits of HD 97658b, a warm, likely volatile-rich super-Earth 
    Dragomir, Diana; Matthews, Jaymie M.; Eastman, Jason D.; Cameron, Chris; Howard, Andrew W.; Guenther, David B.; Kuschnig, Rainer; Moffat, Anthony F. J.; Rowe, Jason F.; Rucinski, Slavek M. (IOP Publishing Limited, 2013-07-20)
    Through photometric monitoring of the extended transit window of HD 97658b with the MOST space telescope, we have found that this exoplanet transits with an ephemeris consistent with that predicted from radial velocity ...

    MOST photometry of the RRd Lyrae variable AQ Leo: two radial modes, 32 combination frequencies and beyond 
    Guenther, David B.; Gruberbauer, Michael; Kolenberg, Katrien; Rowe, Jason F.; Huber, Daniel; Matthews, Jaymie M.; Reegen, Piet; Kuschnig, Rainer; Cameron, Chris; Kallinger, T. (Oxford University Press, 2007-08)
    Highly precise and nearly uninterrupted optical photometry of the RR Lyrae star AQ Leo was obtained with the MOST (Microvariability and Oscillations of Stars) satellite over 34.4 d in 2005 February–March. AQ Leo was the ...

    No Conclusive Evidence for Transits of Proxima b in MOST Photometry 
    Kipping, David M.; Cameron, Chris; Hartman, Joel D.; Davenport, James R.A.; Matthews, Jaymie M.; Sasselov, Dimitar; Rowe, Jason; Siverd, Robert J.; Chen, Jingjing; Guenther, David B. (The American Astronomical Society, 2017-03)
    The analysis of Proxima Centauri's radial velocities recently led Anglada-Escudé et al. to claim the presence of a low-mass planet orbiting the Sun's nearest star once every 11.2 days. Although the a priori probability ...

    Stable and unstable accretion in the classical T Tauri stars IM Lup and RU Lup as observed by MOST 
    Siwak, Michal; Ogloza, Waldemar; Rucinski, Slavek M.; Moffat, Anthony F. J.; Matthews, Jaymie M.; Cameron, Chris; Guenther, David B.; Kuschnig, Rainer; Rowe, Jason F.; Sasselov, Dimitar (Oxford University Press, 2016-03-11)
    Results of the time variability monitoring of the two classical T Tauri stars, RU Lup and IM Lup, are presented. Three photometric data sets were utilized: (1) simultaneous (same field) MOST satellite observations over ...

    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 ...
