PlanetarySeminar: Solar wind and planetary magnetospheres coupling: macrophysical and microphysical processes.

At 14:00 on Wednesday February 8th, 2022, Dr Lina Hadid from LPP, France will be presenting a seminar titled: “Solar wind and planetary magnetospheres coupling: macrophysical and microphysical processes”. The seminar will be accessible via Teams.

Abstract: “Despite many years of research, some properties regarding the dynamical processes of the planetary magnetospheres and in the solar wind an their underlying microphysical processes are still debated and not very well known, in particular such as the turbulence phenomena and the heating processes of the plasma. In fact, compressible turbulence has been a subject of active research within the space physics community for the last three decades and is actually believed to be essential for understanding the physics of the solar wind, of the interstellar medium (in cold molecular clouds) and other astrophysical and space phenomena. In this seminar I will give a review of the different studies that we have done regarding the compressible and incompressible cascade rates in the interplanetary space, as an example of microphysical process. Regarding the microphysical processes, I will present an overview of the Langmuir Probe observations from the Cassini mission during its final phase, the “Grand Finale”, during which the spacecraft crossed the gap between the innermost D ring and the gas giant Saturn.”
