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 ![$\rm [Fe/H]\simeq 0.067$](/articles/aa/abs/2006/05/aa3791-05/aa3791-05_tex_eq1.png)
, an age between
and 
yr and a distance
modulus of 
–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.
