    Frequency Power Spectrum of Stellar Light Variations

    Date: 03 May 2007
    Satellite: CoRoT
    Depicts: Light variation power spectrum for frequencies 1.5 - 2 mHz
    Copyright: CoRoT asteroseismological team

    This plot shows the power spectrum in arbitrary units (P) as a function of frequency (f), for the light curve of a solar type star (see related images). The spectral analysis of the light curve, reveals small periodic components in the expected domain from 1.5 to 2 mHz. These periods, corresponding to modes of oscillation of the star will be studied and interpreted to understand the star's internal structure and determine its age.
