Several candidates for low-order p modes (n less than or equal to 5) and po
ssibly g modes were found by applying mode-detection techniques such as mul
tivariate spectral regression analysis and time-frequency analysis to the V
IRGO full-disc solar irradiance data. Three out of the candidates for low-o
rder p modes could be confirmed by significant peaks in the un-treated powe
r spectra in good agreement with theoretical predictions. The frequency of
a fourth candidate for a low-order p mode lies some 2.8 mu Hz below the pre
dicted frequency. The candidates found for g modes are less reliable, since
none of them could be confirmed neither by significant peaks in the un-tre
ated power spectra nor by the detection of multiplets.
