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.

The morphology of the X-ray afterglows and of the jetted GeV emission in long gamma-ray bursts

The morphology of the X-ray afterglows and of the jetted GeV emission in long gamma-ray bursts In a new article published in the Monthly Notices of the Royal Astronomical Society, an ICRA-ICRANet research team (some of them INAF associates) sheds light on the mass and spin of stellar-mass BHs from an extensive analysis of long-duration GRBs

The best place and time to live in the Milky Way

Mar 05, 2021

The best place and time to live in the Milky Way More than 6 billion years ago, the outskirts of the Milky Way were the safest places for the development of possible life forms, sheltered from the most violent explosions in the universe: gamma-ray bursts and supernovae. This is demonstrated by a new study, led by researchers from INAF and the University of Insubria in Italy, which investigates the incidence of these events throughout the evolution of our galaxy

Magnetic anomalies on the young craters of Mercury

Feb 24, 2021

Magnetic anomalies on the young craters of Mercury It is possible to find a point of convergence between geophysics and planetary geology, and a group of researchers led by Valentina Galluzzi from INAF did so by analyzing the crustal magnetic field of the planet Mercury, focusing on some anomalies identified nearby two recently formed craters
