Plenary 6
- Natasha Jeffrey (Northumbria University)
In-situ measurements and remote-sensing observations have revealed a rich variety of activities in the solar atmosphere and wind, spanning over a huge amount of time and length scales. In this presentation we will focus on two main basic processes which have an important role in the energetics of the solar wind: (1) the turbulent energy transfer of the electromagnetic and kinetic energy with...
Parker Solar Probe has now completed eight orbits around the Sun, providing a new view of the dynamics of the solar wind in the inner heliosphere all the way down to 14.5 Solar Radii from the surface. This presentation will highlight some important early results, such as the prevalence of Alfvénic turbulence in solar wind of all speeds, the dynamics and evolution of switchbacks, the...
The first encounters of PSP with the Sun revealed the presence of ubiquitous localised magnetic deflections, often called “switchbacks”, in the inner heliosphere. Two main class of theories have emerged in order to explain the formation of these structures: the formation by processes occurring deep in the solar atmosphere or directly in the solar wind. The origin of switchbacks is currently...
Space weather previsions require a good balance between speed and accuracy to be able to anticipate the impact of eruptive events at Earth. The strategy used by the european project EUPHORIA 2.0 is to make the best use of various numerical techniques and codes and couple them numerically. This approach however requires a very good description of the corona, as it is the first step of the chain...
