The solar wind: acceleration mechanisms, turbulence and heating

The study of mass loss from the Sun due to the solar wind relies principally on observations from space, both "remote-sensing", using instruments for UV and EUV
images of the solar disk and white light and UV coronographs, as well as via "in situ" measurements of characteristic parameters (velocity, magnetic and electric field, density, temperature). The measurements are necessarily supported by the analysis of theoretical models and by the comparison with the results of high precision numerical simulations.
The Italian community is constantly involved in all the phases of the above mentioned study, both in the development of instruments on-board satellites and numerical codes, as well as data analysis and theoretical modeling. The magnetic turbulence in the solar wind has a decisive influence on the processes that transport energetic particles into interplanetary space. In turn, the transport influences the acceleration processes, like stochastic acceleration and so-called "diffusive shock acceleration".

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.
