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.

NGC 362D: TWO RECORD-BREAKING FINDINGS SHED LIGHT ON THE EVOLUTION OF MILLISECOND PULSARS

NGC 362D: TWO RECORD-BREAKING FINDINGS SHED LIGHT ON THE EVOLUTION OF MILLISECOND PULSARS An INAF- and University of Bologna-led research team has discovered a binary system caught in an exceptionally rare evolutionary stage, consisting of a millisecond pulsar and the youngest white dwarf ever observed in a system of this kind

AN "IMPROBABLE" PLANETARY SYSTEM: COMPACT, COPLANAR, AND SHAPED BY A BROWN DWARF

Jun 17, 2026

AN "IMPROBABLE" PLANETARY SYSTEM: COMPACT, COPLANAR, AND SHAPED BY A BROWN DWARF An international team involving over ten institutions, with a strong participation from ESO and INAF, has characterised TOI-201 c, the transiting brown dwarf with the longest period for which mass has been measured. The study, published today in Nature, reveals a compact, coplanar system in which the presence of a massive, eccentric object redefines the stability boundaries for the inner planets

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.
