RELIABLE ANALYSIS OF POWER AND PHASE FEATURES AS SEEN FROM BISON AND GOLF OBSERVATIONS

摘要

We present results to proof that the phase, together with the power, can be used as new diagnostic tool in the study of the excitation mechanism of solar oscillations. To this aim we compared power and phase temporal features for low l degree modes, using data provided by Birmingham Solar Oscillation Network (BiSON) and Global Oscillation Low Frequency (GOLF) on board of the satellite SOHO. We show, that the temporal features of power and phase show up in the two datasets with the same behaviour, and this validates the use of the phase in our future investigation on the excitation and damping mechanism of solar acoustic waves.
