abstract = {It is well known that the residuals of the multifrequency analysis of δ Scuti
stars are correlated, giving rise to challenging features such as a plateau (HD 50844,
HD 50870, HD 49434, . . . ) of non-resolved frequencies with amplitude higher than the
expected noise level. Several hypotheses have been advanced to explain these features:
effective convection, rotation, non-linear interactions, etc. We have recently demonstrated
that in some cases the underlying function describing the light variations of δ Scuti stars
has not the property of being analytic. The strong consequence of this result is that the
Fourier expansion on which the harmonic analysis is based could be not justified.
In order to know the extension of this phenomenon among δ Scuti stars, we have used
photometric data from CoRoT seismofield and a set of Kepler stars. The results show
that this inconsistency in the application of harmonic analysis is almost ubiquitous to the
δ Scuti pulsating stars.},
