Scientific paper

Normal mode spectra and neutrino counting rate calculations are presented for a set of chemically inhomogeneous solar models which have a high heavy element core concentration, and a high opacity which makes the core convective, while the envelope structure is that of the standard model. It is demonstrated that the g mode spectra become less densely separated than would be the case for the standard model, simplifying the interpretation of the 160-min oscillations. In addition, it is noted that low neutrino counting rates are achievable for a low He initial core concentration. The present models do not contradict the frequency spacing of global 5-min oscillations.
