The advent of solar seismology is widely recognized as the independent discoveries by Leighton, Noyes Simon (1963) and Evans, Michard Servajean (1962) of Doppler oscillations in the Suns surface, mostly with periods ranging from about 2 to 8 minutes. This was recognized as the surface signature of waves traveling beneath the Suns surface. These waves, now understood to be generated by convection a few hundred km beneath the Suns surface (Stein et al. , 2004), penetrate deep beneath the surface, illing the solar interior. The idea of using observations of these waves as a diagnostic of the Sunas interior structure was introduced by Ulrich (1970), and developed at length by Deubner (1975) and Rhodes, Ulrich Simon (1977). Continued development followed many different avenues, some of these similar in some ways to geoseismic diagnostics of the Earths interior. Indeed, helioseismic holography and migration theory, the latter developed by Claerbout (1970) for applications in geoseismology, share basic concepts in wave optics in very similar contexts. However, solar seismology has overwhelming advantages, both in the quality, extent and uniformity of the observations and in the optical quality of the solar interior as an acoustic medium. Solar seismology gave us maps of the solar interior rotation rate (Rhodes, Deubner Ulrich , 1979), afirming that the Sun is a differentially rotating iuid, its convection zone continuously being warped as the equatorial region rotates signifcantly faster than the inner polar region and the outer equatorial convection zone rotates faster than the deep convection zone. Helioseismology is also the signifcant observational basis of our present understanding of the thermal structure of the solar interior in standard models such as Christensen-Dalsgaard, Profitt Thompson (1993).
