    MOST space-based photometry of the transiting exoplanet system HD 189733: precise timing measurements for transits across an active star 
    Guenther, David B.; Miller-Ricci, Eliza; Rowe, Jason F.; Sasselov, Dimitar; Matthews, Jaymie M.; Kuschnig, Rainer; Croll, Bryce; Moffat, Anthony F. J.; Rucinski, Slavek M.; Walker, Gordon A. H. (American Astronomical SocietyIOP Publishing, 2008-07-20)
    We have measured transit times for HD 189733b passing in front of its bright (V = 7.67), chromospherically active, and spotted parent star. Nearly continuous broadband optical photometry of this system was obtained with ...
