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.

ALMA WITNESSES STAR BIRTH BEYOND THE EDGES OF THE MILKY WAY

Apr 22, 2026

ALMA WITNESSES STAR BIRTH BEYOND THE EDGES OF THE MILKY WAY A new study, led by INAF, has mapped, for the first time, the mass distribution of newly formed cores in the Large Magellanic Cloud. Thanks to high-resolution images from ALMA, it has emerged that these cores form according to the same patterns observed in the Milky Way. The result suggests that the initial fragmentation mechanisms of gas and dust clumps, from which stars are born, are universal and independent of the galactic environment.

CALVERA EXPLODED WHERE IT SHOULDN’T HAVE: A “RUNAWAY” PULSAR DEFIES THE RULES OF THE MILKY WAY

CALVERA EXPLODED WHERE IT SHOULDN’T HAVE: A “RUNAWAY” PULSAR DEFIES THE RULES OF THE MILKY WAY A stellar explosion, a pulsar, and a supernova remnant - that’s the story of Calvera. Positioned more than 6,500 light-years above the Galactic plane, this system is rewriting what we know about stellar evolution in our galaxy. The research originates from a team at the Italian National Institute for Astrophysics (INAF), in collaboration with the University of Palermo, and is detailed in a study published in Astronomy & Astrophysics
