Solar astrophysics and interplanetary physics

The scientific objective of research in solar, interplanetary and magnetospheric physics, is the understanding of the variety of phenomena related to solar activity and its influence on planetary environments. This field of investigation, that explores in detail a rich variety of physical processes, important also in a more general astrophysical context, can be summarised as the study of the complex interaction between magnetic fields and plasmain a wide range of dynamical conditions. Recent years have seen significant progress in our understanding of the Sun and heliosphere, thanks to the use of new and more effective instruments, both from the ground and from space. Also, a series of instruments dedicated to the study of the properties of the terrestrial ionosphere and magnetosphere and their variations, has identified correlations between changes in the circum-terrestrial environment, whose impact on human activity can be critical, with interplanetary perturbations induced by the most energetic, solar, magnetic phenomena (flares, eruptive prominences, coronal mass ejections), encouraging significantly studies of the physics of the Sun-Earth relationship and "Space Weather".

The Italian solar, interplanetary and magnetospheric scientific community is actively involved in these fields of investigation, regularly making use of available international instrumentation both on the ground and in space, and has also contributed significantly to the building of the same instruments. Further, the community also has available adistributed observational infrastructure both nationally and abroad, constantly used forsystematic observations of the Sun and the study of Sun-Earth relations.

An INAF study provides new assumptions on oscillation in star layers A team of researchers led by Enrico Corsaro, fellow of the AstroFIt2 programme at INAF in Catania, has recently published a study in Nature Astronomy which shows the relationship between the orientation of the stellar-spin axis and the environment where they formed.

INAF researchers participate in the discovery of two Super Earths Two massive rocky planets 21 light-years from us, the closest known among those transiting in front of their parent star, have been detected and studied thanks to TNG Galileo National Telescope observations.

Risparmio e vedo il cielo. INAF joins the “M’illumino di meno” campaign

Risparmio e vedo il cielo. INAF joins the “M’illumino di meno” campaign On 24 February, on the occasion of the Energy Saving Day 2017, the National Institute for Astrophysics – INAF has joined the M’illumino di Meno campaign launched by Radio Rai 2 show Caterpillar, now in its thirteenth year, which renews the invitation to turn off the lights in squares, private and public lightings across Italy.
