Abstract
The exoplanetary surveys in radial-velocity or in photometry need to have a good knowledge of the magnetic activity. For instance, they have to understand the main shape of stellar activity and spots properties to choose the best targets for the search of low-mass planets in the habitable zone of their stars (Boisse et al. 2011, Dumusque et al. 2011) or to derive the good parameters from the transit observations (Boisse et al. in prep., Oshagh et al. in prep.). With that aim, these studies lead already to give properties on the magnetic activity like on active cycles (Lovis et al. 2011) or on active longitudes (Sanchis-Ojeda et al. 2011), that give important indications to constrain stellar dynamos.
