Description
In this work we propose a preliminary seismic investigation of $delta$
Scuti stars in the Pleiades cluster, focusing on potential diagnostics
of convection and core-overshooting. Taking into account the effect of
fast rotation in the modelling, we compare observed frequencies for 4
$delta$ Scuti stars with radial linear instability predictions. A
satisfying agreement is reached between the predicted ranges of unstable
modes and those derived from observations for ``low-mass'' stars ($sim
1.55 M_{odot}$). However, a strong disagreement is found for
``high-mass'' stars ($sim 1.77 M_{odot}$), whatever the mixing length
$(alpha)$ value. These results are compared with previous ones obtained
for Praesepe.
