Stellar activity of planetary host star HD 189733
I. Boisse, C. Moutou, A. Vidal-Madjar +20
Extra-solar planet search programs require high-precision velocity measurements. They need to study how to disentangle radial-velocity variations due to Doppler motion from the noi…
MOST detects variability on tau Bootis possibly induced by its planetary companion
Gordon A. H. Walker, Bryce Croll, Jaymie M. Matthews +8
(abridged) There is considerable interest in the possible interaction between parent stars and giant planetary companions in 51 Peg-type systems. We demonstrate from MOST satellite…
MOST Spacebased Photometry of the Transiting Exoplanet System HD 189733: Precise Timing Measurements for Transits Across an Active Star
E. Miller-Ricci, J. F. Rowe, D. Sasselov +8
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 photom…
Looking for Super-Earths in the HD 189733 System: A Search for Transits in Most Space-Based Photometry
Bryce Croll, Jaymie M. Matthews, Jason F. Rowe +10
We have made a comprehensive transit search for exoplanets down to ~1.5 - 2 Earth radii in the HD 189733 system, based on 21-days of nearly uninterrupted broadband optical photomet…
