Description
The present paper discusses the seismic modelling of five δ Scuti stars belonging to the Praesepe cluster. Linear analysis is confronted with observations, using refined descriptions for the effects of rotation on the determination of the global stellar parameters and on the adiabatic oscillation frequency computations. A single, complete, and coherent solution for all the selected stars is found, which implies important constraints to the convection description for a certain range of effective temperatures. Furthermore, an estimate of the global parameters of the selected stars is given which allows us to constrain the cluster global characteristics.
