- Abstract
This work is intended to illustrate the possibilities offered by the CoRoT satellite observations to study the different instability strips (IS), and through them, physical processes and specific features of stellar interiors. The CoRoT space mission, launched on December 27^{th} 2006, has been developped and is operated by CNES, with the contribution of Austria, Belgium, Brasil , ESA, Germany and Spain. It enabled us to observe oscillations from stars down to a noise level of less than a ppm, much lower than the limit usually obtained from the ground. The number of available targets will have more than tripled by the end of the mission
and these data might help testing the "purity" of the IS (i.e. the presence/absence of photometrically constant stars within) and lead to the discovery of new classes of pulsating stars (Degroote et al. 2008). We address this problem in the frame of the B and A main sequence stars.
