Abstract

The frequency difference between a model used only two-point interpolation of opacity and a model used piecewise linear interpolation of opacity 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.<br />Comment: 2 pages, 1 figure; to appear in the Proceedings of IAU Symp. 252 "The Art of Modelling Stars in the 21st Century", Sanya, China, 6th-11th April 2008, (L.
