Solar interior and solar dynamo
The study of solar acoustic modes over the last decades has allowed the interior ofour star to be reconstructed with extreme accuracy (stratification, internal rotation andcomposition), providing critical information on its evolution, composition, dynamics andactivity. The contribution from helioseismology has also been fundamental in the solution of the solar neutrino problem, providing an experimental confirmation of the Standard Solar Model. Italian astronomers have been involved in studies and observations of solar oscillations for many years, participating in the largest helioseismological experiments. The Italian helioseismology community is one of the 10 members of the "HELAS" network, the European Helio and Asteroseismology Network.
