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".

Thanks to the HARPS-N spectrograph, the TNG can see Venus

Thanks to the HARPS-N spectrograph, the TNG can see Venus TThe HARPS-N spectrograph succeeded in measuring from the Earth the velocity of the clouds in the atmosphere of Venus thanks to its high precision, competing with the Japanese Akatsuki probe, which has recently begun to study the atmosphere of the second planet.

The X-ray Universe 2017

Feb 03, 2017

The X-ray Universe 2017 The symposium (Rome, 6-9 June 2017) is the fifth meeting in the series of the international symposia "The X-ray Universe". The intention is to gather a general collection of research in high energy astrophysics. The symposium will provide a showcase for results, discoveries and expectations from current and future X-ray missions.

IXPE mission: Italy and NASA for new X-ray astronomy

Jan 21, 2017

IXPE mission: Italy and NASA for new X-ray astronomy NASA has announced that it is funding a new mission to study the high-energy Universe: it will be called IXPE (Imaging X-Ray Polarimetry Explorer) and will allow astronomers to explore with unprecedented details some of the most extreme astronomic objects, including stellar and supermassive black holes, neutron stars and pulsars. The mission, scheduled for the end of 2020, will count on a considerable Italian contribution through the Italian Space Agency(ASI), the National Institute for Nuclear Physics (INFN) and the National Institute of Astrophysics (INAF).
