In several oportunities, we felt the need to simulate light curves with characteristics representative of what can be expected for COROT. This was the case in several H&H exercises held within the Data Analysis team.

We here propose such a simulator that includes variations due to solar-like oscillations, stellar granulation, stellar magnetic activity and instrumental (photon) as expected for COROT. At the moment, perturbations expected at the harmonics of the orbital period have been excluded but further versions of the package will include such perturbations. Check this page regularly for these new versions.

The package contains an IDL routine, associated auxiliary files and a README.

The figure below shows an example obtained for a 150 day time series for a mV=8, 1.50Mo star, aged of 2.4 Gyr. The power spectrum includes the different components of the simulated signal: oscillations, granulation, magnetic activity and photon noise).
