Scientific paper

A solar model with all the iron condensed out in the matter below the convection zone is studied, along with two others with weakly interactive massive particles (cosmions) orbiting the solar center and producing there a lower effective opacity for radiation flow. A calibration model with normal iron and no cosmions, and without the opacity adjustment, is also presented. Frequency differences between the radial and quadrupole modes one radial order apart are smaller in the no iron and cosmion models than for standard models. In the no iron case, the reduction of the differences is not large; however, for the cosmion cases, these differences are smaller than those measured. Predictions of g-mode period spacings and the stability of the low-degree g-modes are given.
