  • Magnetic activity in the photosphere of CoRoT-Exo-2a. Active longitudes and short-term spot cycle in a young Sun-like star 

    Lanza, A. F.; Pagano, I.; Leto, G.; Messina, S.; Aigrain, Suzanne; Alonso, R.; Auvergne, M.; Baglin, A.; Barge, P.; Bonomo, A. S.; Boumier, P.; Collier Cameron, A.; Comparato, M.; Cutispoto, G.; De Medeiros, J. R.; Foing, B.; Kaiser, A.; Moutou, C.; Parihar, P. S.; Silva-Valio, A.; Weiss, W. W. (EDP Sciences, 2009)
    Context. The space experiment CoRoT has recently detected transits by a hot Jupiter across the disc of an active G7V star (CoRoTExo-2a) that can be considered as a good proxy for the Sun at an age of approximately 0.5 ...
  • Modelling solar-like variability for the detection of Earth-like planetary transits. II. Performance of the three-spot modelling, harmonic function fitting, iterative nonlinear filtering, and sliding boxcar filtering 

    Bonomo, A. S.; Aigrain, Suzanne; Bordé, P.; Lanza, A. F. (EDP Sciences, 2009)
    Aims. As an extension of a previous work, we present a comparison of four methods of filtering solar-like variability to increase the efficiency of detection of Earth-like planetary transits by means of box-shaped transit ...
  • Photospheric activity and rotation of the planet-hosting star CoRoT-4a 

    Lanza, A. F.; Aigrain, Suzanne; Messina, S.; Leto, G.; Pagano, I.; Auvergne, M.; Baglin, A.; Barge, P.; Bonomo, A. S.; Collier Cameron, A.; Cutispoto, G.; Deleuil, M.; De Medeiros, J. R.; Foing, B.; Moutou, C. (EDP Sciences, 2009)
    Aims. The space experiment CoRoT has recently detected a transiting hot Jupiter in orbit around a moderately active F-type mainsequence star (CoRoT-4a). This planetary system is of particular interest because it has an ...

W.; Guillot, T.; Hartmann, M.; Hatzes, A.; Hébrard, G.; Jorda, L.; Lammer, H.; Léger, A.; Llebaria, A.; Lovis, C.; Magain, P.; Mayor, M.; Mazeh, T.; Moutou, C.; Ofir, A.; Pätzold, M.; Pepe, F.; Pont, F.; Queloz, D.; Rabus, M.; Rauer, H.; Régulo, C.; Renner, S.; Rouan, D.; Samuel, B.; Santerne, A.; Schneider, J.; Shporer, A.; Stecklum, B.; Tingley, B.; Udry, S.; Wuchterl, G. (EDP Sciences, 2009)
    Aims. We present here the list of planetary transit candidates detected in the first long run observed by CoRoT: LRc01, towards the galactic center in the direction of Aquila, which lasted from May to October 2007. Methods. ...
  • The secondary eclipse of CoRoT-1b 

    Alonso, R.; Alapini, Aude; Aigrain, Suzanne; Auvergne, M.; Baglin, A.; Barbieri, M.; Barge, P.; Bonomo, A. S.; Bordé, P.; Bouchy, F.; Chaintreuil, S.; De la Reza, R.; Deeg, H. J.; Deleuil, M.; Dvorak, R.; Erikson, A.; Fridlund, M.; De Oliveira Fialho, F.; Gondoin, P.; Guillot, T.; Hatzes, A.; Jorda, L.; Lammer, H.; Léger, A.; Llebaria, A.; Magain, P.; Mazeh, T.; Moutou, C.; Ollivier, M.; Pätzold, M.; Pont, F.; Queloz, D.; Rauer, H.; Rouan, D.; Schneider, J.; Wuchterl, G. (EDP Sciences, 2009)
    The transiting planet CoRoT-1b is thought to belong to the pM-class of planets, in which the thermal emission dominates in the optical wavelengths. We present a detection of its secondary eclipse in the CoRoT white channel ...
