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".

INAF researcher involved in the discovery of a millisecond pulsar An international team of astronomers led by Ivan Zolotukhin of the Institut de Recherche en Astrophysique et Planétologie (IRAP) of Toulouse, also including Matteo Bachetti, a researcher of the INAF in Cagliari, has discovered that this pulsar is at the beginning of the recycle phase, i.e. the process that causes slow and "turned-off” neutron stars to turn on again as “millisecond pulsar”.

Cassini Scientist for a Day: the competition for young scientists sets new records

May 20, 2017

Cassini Scientist for a Day: the competition for young scientists sets new records New record numbers for the 15th edition of Cassini Scientist for a Day, the international competition launched by NASA and promoted in Europe by the European Space Agency (ESA), open to lower and upper secondary school students. In Italy, 181 students participated in the competition, sending a total of 81 essays to a panel of researchers and experts in science communication.
