  • 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 ...
  • Rate and nature of false positives in the CoRoT exoplanet search 

    Almenara, J.-M.; Deeg, H. J.; Aigrain, Suzanne; Alonso, R.; Auvergne, M.; Baglin, A.; Barbieri, M.; Barge, P.; Bordé, P.; Bouchy, F.; Bruntt, H.; Cabrera, J.; Carone, L.; Carpano, S.; Catala, C.; Csizmadia, Sz.; De la Reza, R.; Deleuil, M.; Dvorak, R.; Erikson, A.; Fridlund, M.; Gandolfi, D.; Gillon, M.; Gondoin, P.; Guenther, E. W.; Guillot, T.; Hatzes, A.; Hébrard, G.; Jorda, L.; Lammer, H.; Léger, A.; Llebaria, A.; Loeillet, B.; Magain, P.; Mayor, M.; Mazeh, T.; Moutou, C.; Ollivier, M.; Pätzold, M.; Pont, F.; Queloz, D.; Rauer, H.; Régulo, C.; Renner, S.; Rouan, D.; Samuel, B.; Schneider, J.; Shporer, A.; Wuchterl, G.; Zucker, S. (EDP Sciences, 2009)
    Context. The CoRoT satellite searches for planets by applying the transit method, monitoring up to 12,000 stars in the galactic plane for 150 days in each observing run. This search is contaminated by a large fraction of ...
  • 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. J.; De la Reza, R.; Deleuil, M.; Dvorak, R.; Erikson, A.; Fridlund, M.; Gondoin, P.; Jorda, L.; Lammer, H.; Léger, A.; Llebaria, A.; Magain, P.; Moutou, C.; Ollivier, M.; Pätzold, M.; Pont, F.; Queloz, D.; Rauer, H.; Rouan, D.; Sabo, R.; Schneider, J.; Wuchterl, G. (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. IV. CoRoT-Exo-4b: a transiting planet in a 9.2 day synchronous orbit 

    Aigrain, Suzanne; Collier Cameron, A.; Ollivier, M.; Pont, F.; Jorda, L.; Almenara, J.-M.; Alonso, R.; Barge, P.; Bordé, P.; Bouchy, F.; Deeg, H. J.; De la Reza, R.; Deleuil, M.; Dvorak, R.; Erikson, A.; Fridlund, M.; Gondoin, P.; Gillon, M.; Guillot, T.; Hatzes, A.; Lammer, H.; Lanza, A. F.; Léger, A.; Llebaria, A.; Magain, P.; Mazeh, T.; Moutou, C.; Pätzold, M.; Pinte, C.; Queloz, D.; Rauer, H.; Rouan, D.; Schneider, J.; Wuchterl, G.; Zucker, S. (EDP Sciences, 2008)
    CoRoT, the first space-based transit search, provides ultra-high-precision light curves with continuous time-sampling over periods of up to 5 months. This allows the detection of transiting planets with relatively long ...
  • Transiting exoplanets from the CoRoT space mission. VI. CoRoT-Exo-3b: the first secure inhabitant of the brown-dwarf desert 

    Deleuil, M.; Deeg, H. J.; Alonso, R.; Bouchy, F.; Rouan, D.; Auvergne, M.; Baglin, A.; Aigrain, Suzanne; Almenara, J.-M.; Barbieri, M.; Barge, P.; Bruntt, H.; Bordé, P.; Collier Cameron, A.; Csizmadia, Sz.; De la Reza, R.; Dvorak, R.; Erikson, A.; Fridlund, M.; Gandolfi, D.; Gillon, M.; Guenther, E.
