Abstract

We analyzed the light curves of RR Lyrae stars in the the first long run field (LRc01) of the CoRoT mission. A high incidence rate of the Blazhko phenomenon was found in the RRab sample. Two of these stars are blended and exhibit low amplitude pulsation. Utilizing the outstanding photometric accuracy of CoRoT we derived accurate instantaneous amplitudes and periods and compared the amplitude and phase modulation properties of the CoRoT Blazhko stars.
