dc.descriptionIn this work we propose a preliminary seismic investigation of $δ$ 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 $δ$ 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 $(α)$ value. These results are compared with previous ones obtained for Praesepe.
