Seismology of the sun and other stars

Important results have already been obtained from helioseismology. As far as the solar structure is concerned, their most striking feature is perhaps how closely they agree with conventional solar models; this suggests that the solar neutrino problem may require a physical, rather than astrophysical, solution. However, the apparently complacent conclusion should not overshadow the fact that there remain substantial discrepancies, which are not understood, between the observed and computed oscillation frequencies. The inferred solar rotation curve is very far from expectations, and clearly raises important questions concerning the evolution of the solar internal rotation and the generation of the solar magnetic field. The observations now underway or being planned will contribute substantially to elucidating these problems.
