Recent studies have established that peaks in solar oscillation power spectraare not Lorentzian in shape, but have a distinct asymmetry. Fitting a symmetricLorentzian profile to the peaks therefore produces a shift in frequency of themodes. Accurate determination of low-frequency modes is essential to infer thestructure of the solar core by inversion of the mode frequencies. In this paperwe investigate how the changes in frequencies of low-degree modes obtained byfitting symmetric and asymmetric peak profiles change the inferred propertiesof the solar core. We use data obtained by the Global Oscillations at LowFrequencies (GOLF) project on board the SoHO spacecraft. Two different solarmodels and inversion procedures are used to invert the data to determine thesound speed in the solar core. We find that for a given set of modes nosignificant difference in the inferred sound-speed results from takingasymmetry into account when fitting the low-degree modes.Comment: To appear in Ap
