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.

Magnetic tornadoes in the Sun’s atmosphere A team of researchers led by Mariarita Murabito (INAF) that includes scientists of the Italian Space Agency (ASI) and the Warwick University has provided the first observational proof that solar tornadoes are produced by swirling magnetic fields

Ultraviolet light vs. COVID19: from the Sun to artificial lamps the germicidal power of ultraviolet rays against the pandemic

Ultraviolet light vs. COVID19: from the Sun to artificial lamps the germicidal power of ultraviolet rays against the pandemic Results of a study carried out by the Italian National Institute for Astrophysics (INAF) and the University of Milan, in collaboration with Istituto Nazionale Tumori and the Don Gnocchi Foundation of Milan, demonstrate the high germicidal power of short ultraviolet radiation (UV-C) on SARS-COV-2 coronavirus. This result has important public health implications on the strategies to be adopted to manage the pandemic and clearly explain how decontamination and sterilization protocols to prevent SARS-Cov-2 infection must be designed. Notably, taking off from these results a second study explains the role of Sun-derived UV-B/A in conditioning the epidemiology and the worldwide evolution of the COVID-19 pandemic
