Scientific paper

It is proposed to use cross correlation and autocorrelation methods to test the presence of g-modes in a real power spectrum. This method is used on 3 yr of ACRIM irradiance data with negative conclusions. It is also tested with synthetic g-modes computed into a standard and a nonstandard model. Only the standard model seems to offer enough regularity in rotational splitting and in period separation to make reliable the measurement of these two parameters.
