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.

Light in Astronomy 2017

Nov 14, 2017

Light in Astronomy 2017 Light in Astronomy, organized by INAF in collaboration with the Italian Astronomical Society-SAIt, will be a week (13-19 November) dedicated to satisfying curiosity about the Universe thanks to the opening in Italy of INAF premises, including the astronomical observatories.

Marsis radar reveals that on Mars all that echoes is not ice

Marsis radar reveals that on Mars all that echoes is not ice The low dielectric constant of the Meridiani Planum deposits is consistent with a thick layer of ice-free, porous, basaltic sand. This study is fundamental to identify techniques that may help find the planet’s areas with accessible water ice.

A 3D step towards sorting out the Gamma-Ray Bursts zoo

A 3D step towards sorting out the Gamma-Ray Bursts zoo A powerful tool for characterizing and classifying gamma-ray bursts (GRBs) to allow their use as tracers of the expansion history of the universe has recently been presented by an international team of researchers led by Dr. Maria Dainotti
