The measurements made from space by the HF/NIMBUS, ACRIM/SMM-UARS, VIRGO/SoHO radiometers, during the last three activity cycles, have shown that the total solar radiation varies in phase with the magnetic activity of the Sun. The study of phenomena that determine the variability of the Sun, and the acquisition of data useful for its study, are carried out by INAF, in collaboration with research groups at the Universities of Rome "Tor Vergata" and Calabria, and the INGV-Rome.

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

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.
