A seismological analysis of δ Scuti stars in the Pleiades cluster

A comparison between the oscillation frequencies of six multi-periodic delta 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] similar or equal to 0.067, an age between 70 x 10(6) and 100 x 10(6) yr and a distance modulus of m(V) - M-V = 5.60-5.70 mag. 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.
