Abstract (from CDS):

A comparison between the oscillation frequencies of six multi-periodic δ Scuti stars of the Pleiades cluster and the eigenfrequencies of rotating stellar models that match the corresponding stellar parameters has been carried out. The assumption that all the stars considered have some common parameters, such as metallicity, distance or age, is imposed as a constraint. As a result, we have a best fit solution associated with a cluster metallicity of [Fe/H]≃0.067, an age between 70x106 and 100x106yr and a distance modulus of mV-MV=5.60-5.70mag. All the stars were found to oscillate mainly in non-radial, low degree, low order p modes. Estimates of mass and rotation rates for each star are also obtained.
