Quaternionic Transform: A new Light on the Solar Power Spectrum

Asteroseismology, that is, the use of frequency content a time series caused by variations in brightness or radial velocity stellar object, is based on hypothesis such harmonic and therefore can be described sum sines cosines. If this were not case (e.g., oscillations an ellipsoid revolution) it cannot guaranteed Discrete Fourier transform least squares approximation to series. This report studies effect extending kernel particular quaternion exploring impact when applied best we have (GOLF/SoHO) from closest star, our Sun. The results are consistent with notable improvement signal-to-noise ratio low range. opens possibility detecting elusive g modes Sun future works.
