Asteroseismic constraints on the OPAL opacity interpolation

摘要：

There is a difference of a few Kelvins in the effective temperature between a model used only two-point interpolation of opacity and a model used piecewise linear interpolation of opacity. However the frequency difference between the models is of the order of several microHertz at a certain stage,which is almost 10 times worse than the observational precision of p-modes of solar-like stars. Therefore,the two-point interpolation of opacity is unsuitable in modelling of solar-like stars with element diffusion.
