Solar neutrino experiments have provided unique information about the energy-generating core, while helioseismology has provided information about the rest of the Sun.
Academic text (1995) -
Studies of the internal structure of the Sun by observing solar vibrations (helioseismology) showed that the predictions of the standard solar model for the temperatures in the central regions of the Sun were consistent with the observations to an accuracy of at least 0.1%.

Surface Forms
Morphology
helioseismology = seismology (semi-transparent) = helio + seism + ology
The word is formed by adding the scientific prefix 'helio-' to the already specialized term 'seismology', so the structure is clear but not fully familiar to average learners.
Etymology
The word helioseismology comes from helio- 'sun', seismo- 'shake', as in seismic which is about earthquakes, and -logy 'study'. So it means the 'study of the Sun's shakes', and scientists use those waves and vibrations to learn what is inside the Sun.
