Abstract: Since the Fourier transform does not provide a complete information on a signal, time/frequency analysis can yield interesting additional results when applied to helioseismic data. It appears that some characteristics of solar p-modes, as central frequency or energy, have short term variations. This information must be taken into account in order to extend our understanding of solar oscillations.
