    Looking for super-Earths in the HD 189733 system: a search for transits in MOST space-based photometry 
    Croll, Bryce; Matthews, Jaymie M.; Rowe, Jason F.; Gladman, Brett; Miller-Ricci, Eliza; Sasselov, Dimitar; Walker, Gordon A. H.; Kuschnig, Rainer; Lin, Douglas N. C.; Guenther, David B. (American Astronomical Society, 2007-12-20)
    We have made a comprehensive transit search for exoplanets down to [similar or equal to]1.5-2 Earth radii in the HD 189733 system, based on 21 days of nearly uninterrupted broadband optical photometry obtained with the ...

    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 ...

    A super-Earth transiting a naked-eye star 
    Winn, Joshua N.; Matthews, Jaymie M.; Dawson, Rebekah I.; Fabrycky, Daniel; Holman, Matthew J.; Kallinger, Thomas; Kuschnig, Rainer; Sasselov, Dimitar; Dragomir, Diana; Guenther, David B. (IOP Publishing Limited, 2011-08-10)
    We have detected transits of the innermost planet “e” orbiting 55 Cnc (V = 6.0), based on two weeks of nearly continuous photometric monitoring with the MOST space telescope. The transits occur with the period ...
