Sounding the Solar Interior

Serious research on the solar internal structure began in the second half of nineteenth century. Attempts were made to asses physical parameters in the interior and, first of all, to explain the source of the energy radiated by the Sun. Already sir Arthur Eddington in his The internal constitution of the stars published in 1926 presents the hypothesis that the energy is liberated in building up helium nucleus from four protons, as most plausible explanation. By early 1940ies, mostly thanks to works of Hans Bethe, the basic chains of nuclear reactions leading to formation of helium nuclear reactions were known. At this time all basic physics needed to construct models of the Sun’s interior became available. However, important improvements are being introduced to these days.
