| Abstract: |
The effect of the OPAL-92 and OP opacity on the frequencies of solar p-modes are studied. It is found that although no one can fit the observational data, the difference of OPAL model and observation frequencies have almost the same slope for different modes, which is more likely to come from the non-adiabatic effect in the outer envelope of the Sun, while the OP results have various slopes for different modes, which is difficult to analyze. Thus, the OPAL opacity is favored in solar model. The difference between a grey atmosphere and the Harvard-Smithsonian solar atmosphere model is small. |
