Scientific paper

By using solar irradiance measurements made at Jungfraujoch and Pic-du-Midi, we were able to detect the strongest solar global p-modes in noisy power spectra, which can be compared directly with those obtained from asteroseismological data. In order to facilitate the interpretation of such periodograms, a practical method is introduced that allows the significance of features to be estimated simultaneously at all frequencies in a spectrum with nonuniform noise distribution. When working with multisite networks, a cross-spectral analysis, based on simultaneous data obtained from two locations, is proposed as a means for distinguishing solar or stellar signals from the contribution of local perturbations. In addition, changing properties of the observed noise induced by the variable transparency contribution are analyzed, and a relationship is derived between the horizontal coherence scale of atmospheric fluctuations and the time scale of the local instabilities. By combining these results with other photometric data, we provide estimates of the limits for future ground-based observations of stellar intensity oscillations.
