    Analysis of MOST light curves of five young stars in Taurus–Auriga and Lupus 3 star-forming regions 
    Siwak, Michal; Rucinski, Slavek M.; Matthews, Jaymie M.; Kuschnig, Rainer; Guenther, David B.; Moffat, Anthony F. J.; Sasselov, Dimitar; Weiss, Werner W. (Oxford University Press, 2011-08)
    Continuous photometric observations of five young stars obtained by the MOST satellite in 2009 and 2010 in the Taurus and Lupus star formation regions are presented. Using light-curve modelling under the assumption of ...

    Analysis of variability of TW Hya as observed by MOST and ASAS in 2009 
    Siwak, Michal; Rucinski, Slavek M.; Matthews, Jaymie M.; Pojmanski, Grzegorz; Kuschnig, Rainer; Guenther, David B.; Moffat, Anthony F. J.; Sasselov, Dimitar; Weiss, Werner W. (Wiley-Blackwell, 2011-02)
    As a continuation of our previous studies in 2007 and 2008, new photometric observations of the T Tauri star TW Hya obtained by the MOST satellite and the All Sky Automated Survey (ASAS) project over 40 d in 2009 with ...

    MOST photometry and DDO spectroscopy of the eclipsing (white dwarf + red dwarf) binary V471 Tau 
    Guenther, David B.; Kaminski, Krzysztof Z.; Rucinski, Slavek M.; Matthews, Jaymie M.; Kuschnig, Rainer; Rowe, Jason F.; Moffat, Anthony F. J.; Sasselov, Dimitar; Walker, Gordon A. H.; Weiss, Werner W. (American Astronomical Society, 2007-09)
    The Hyades K2 V + WD system 471 Tau is a prototype post-common envelope system and a likely cataclysmic binary progenitor. We present 10 days of nearly continuous optical photometry by the MOST (Microvariability and ...

    MOST space-based photometry of the transiting exoplanet system HD 209458: transit timing to search for additional planets 
    Guenther, David B.; Miller-Ricci, Eliza; Rowe, Jason F.; Sasselov, Dimitar; Matthews, Jaymie M.; Kuschnig, Rainer; Moffat, Anthony F. J.; Rucinski, Slavek M.; Walker, Gordon A. H.; Weiss, Werner W. (American Astronomical SocietyIOP Publishing, 2008-07-20)
    We report on the measurement of transit times for the HD 209458 planetary system from photometry obtained with the MOST (Microvariability and Oscillations of Stars) space telescope. Deviations from a constant orbital period ...

    Mu Eridani from MOST and from the ground: an orbit, the SPB component’s fundamental parameters and the SPB frequencies 
    Jerzykiewicz, M.; Lehmann, H.; Niemczura, E.; Molenda- Zakowicz, J.; Dymitrov, W.; Fagas, M.; Guenther, David B.; Hartmann, M.; Hrudkova, M.; Kaminski, K.; Weiss, Werner W. (Oxford University Press, 2013-06)

    MOST time series photometry of μ Eri, an SB1 eclipsing binary with a rapidly rotating SPB primary, is reported and analysed. The analysis yields a number of sinusoidal terms, mainly due to the intrinsic ...

    Photometric variability in FU Ori and Z CMa as observed by MOST 
    Siwak, Michal; Rucinski, Slavek M.; Matthews, Jaymie M.; Kuschnig, Rainer; Guenther, David B.; Moffat, Anthony F. J.; Rowe, Jason F.; Sasselov, Dimitar; Weiss, Werner W. (Oxford University Press, 2013-06)

    Photometric observations obtained by the MOST satellite were used to characterize optical small-scale variability of the young stars FU Ori and Z CMa. Wavelet analysis for FU Ori reveals the possible existence ...

    A search for transits of GJ 581e and characterization of the host star variability using MOST space telescope photometry 
    Dragomir, Diana; Matthews, Jaymie M.; Kuschnig, Rainer; Rowe, Jason F.; Gladman, Brett J.; Guenther, David B.; Moffat, Anthony F. J.; Rucinski, Slavek M.; Sasselov, Dimitar; Weiss, Werner W. (IOP Publishing Limited, 2012-11-01)
    The GJ 581 system has been amply studied since its discovery in 2005: the number of known planets in the system has increased and their orbital parameters are among the most precisely determined for radial-velocity-detected ...

    Solar-like oscillations and activity in Procyon: A comparison of the 2007 MOST and ground-based radial velocity campaigns 
    Huber, Daniel; Bedding, Timothy R.; Arentoft, Torben; Gruberbauer, Michael; Guenther, David B.; Houdek, Gunter; Kallinger, Thomas; Kjeldsen, Hans; Matthews, Jaymie M.; Stello, Dennis; Weiss, Werner W. (American Astronomical SocietyIOP Publishing, 2011-04-20)
    We compare the simultaneous 2007 space-based MOST photometry and ground-based radial velocity (RV) observations of the F5 star Procyon. We identify slow variations in the MOST data that are similar to those reported in the ...

    A stable quasi-periodic 4.18-d oscillation and mysterious occultations in the 2011 MOST light-curve of TW Hya 
    Siwak, Michal; Rucinski, Slavek M.; Matthews, Jaymie M.; Guenther, David B.; Kuschnig, Rainer; Moffat, Anthony F. J.; Rowe, Jason F.; Sasselov, Dimitar; Weiss, Werner W. (Oxford University Press, 2014-10-11)
    We present an analysis of the 2011 photometric observations of TW Hya by the MOST satellite; this is the fourth continuous series of this type. The large-scale light variations are dominated by a strong, quasi-periodic ...
