Description
We showed in previous works that a periodic pattern could be found in
the frequency set of δ Sct stars observed by CoRoT. We related
that pattern with a value of the large separation. However, are these
stars particular cases? We present here preliminary results of our work
aimed at answering this and related questions. We looked for
periodicities in the frequency spectrum of a sub-sample of 153 δ
Sct pulsators observed by Kepler. We have determined that ˜ 50% of
the sub-sample shows a clear pattern. Moreover, we found three objects
with almost the same KIC physical parameters showing the same value of
the pattern. We suggest that the pattern is a sign of a
large-separation-like structure.
