摘要：
Most helioseismic analyses are based on solar oscillation frequencies obtained by fitting symmetric peak profiles to the power spectra. However, it has now been demonstrated that the peaks are not symmetric. In this work we study the effects of the asymmetry of the peak profiles on the solar oscillation frequencies of p-modes for low and intermediate degrees. We also investigate how the resulting shift in frequencies affects helioseismic inferences.
