Description
In the present work, we study correlations between stellar fundamental
parameters and the oscillation amplitude for delta Scuti stars. We
present this study for a sample of 17 selected delta Scutis belonging to
5 young open clusters. Taking advantage of properties of delta Scutis in
clusters, we correct the photometric parameters of our objects for the
effects of fast rotation. We confirm the benefit of applying such
corrections in this kind of studies. In addition, the technique used for
this correction allows us to obtain an estimate of stellar parameters
such as the angle of inclination and the rotation rate, usually not
accessible. A significant correlation between the parameter
i'(estimation of the angle of inclination of the star) and
the oscillation amplitude is found. A discussion and interpretation of
these a priori surprising results is proposed, in terms of a possible
selection rule for oscillation modes of delta Scuti stars.
