Abstract

Several hypotheses have been advanced to explain the wealthy spectra of space observed intermediate mass pulsating stars. Among which we can find the rotational splitting, stochastic excitation or detection of coloured noise due to superficial granulation. An overview of the problem requires a coherent analysis of a large number of stars looking for correlations between the observed frequency spectra and the position on the HR diagram.
