  • Comparative blind test of five planetary transit detection algorithms on realistic synthetic light curves 

    Moutou, C.; Pont, F.; Barge, P.; Aigrain, Suzanne; Auvergne, M.; Blouin, D.; Cautain, R.; Erikson, A.; Guis, V.; Guterman, P.; Irwin, Mike; Lanza, A. F.; Queloz, D.; Rauer, H.; Voss, H.; Zucker, S. (EDP Sciences, 2005)
    Because photometric surveys of exoplanet transits are very promising sources of future discoveries, many algorithms are being developed to detect transit signals in stellar light curves. This paper compares such algorithms ...
  • Noise properties of the CoRoT data. A planet-finding perspective 

    Aigrain, Suzanne; Pont, F.; Fressin, F.; Alapini, Aude; Alonso, R.; Auvergne, M.; Barbieri, M.; Barge, P.; Bordé, P.; Bouchy, F.; Deeg, H. J.; De la Reza, R.; Deleuil, M.; Dvorak, R.; Erikson, A.; Fridlund, M.; Gondoin, P.; Guterman, P.; Jorda, L.; Lammer, H.; Léger, A.; Llebaria, A.; Magain, P.; Mazeh, T.; Moutou, C.; Ollivier, M.; Pätzold, M.; Queloz, D.; Rauer, H.; Rouan, D.; Schneider, J.; Wuchterl, G.; Zucker, S. (EDP Sciences, 2009)
    In this short paper, we study the photometric precision of stellar light curves obtained by the CoRoT satellite in its planet-finding channel, with a particular emphasis on the time scales characteristic of planetary ...
  • Removing systematics from the CoRoT light curves. I. Magnitude-dependent zero point 

    Mazeh, T.; Guterman, P.; Aigrain, Suzanne; Zucker, S.; Grinberg, N.; Alapini, Aude; Alonso, R.; Auvergne, M.; Barbieri, M.; Barge, P.; Bordé, P.; Bouchy, F.; Deeg, H.

(EDP Sciences, 2009)
    This paper presents an analysis that searched for systematic effects within the CoRoT exoplanet field light curves. The analysis identified a systematic effect that modified the zero point of most CoRoT exposures as a ...
  • Transiting exoplanets from the CoRoT space mission. VIII. CoRoT-7b: the first super-Earth with measured radius 

    Léger, A.; Rouan, D.; Schneider, J.; Barge, P.; Fridlund, M.; Samuel, B.; Ollivier, M.; Guenther, E. W.; Deleuil, M.; Deeg, H.

(2009)
    Aims. We report the discovery of very shallow (ΔF/F ≈ 3.4×10−4), periodic dips in the light curve of an active V = 11.7 G9V star observed by the CoRoT satellite, which we interpret as caused by a transiting companion. We ...
