International audience ; One of the outstanding scientific questions in space physics is how charged particles are accelerated up to supra-thermal energies and how they are transported through the inner heliosphere. Such problems match some of the scientific objectives of the Solar Orbiter Science Activity Plan and represent the main scientific cases discussed in the Italian SWA-Solar Orbiter Working Group (WG) on "Particle Energization" (https://sites.google.com/view/italian-solar-orbiter-swa/research-interests/particle-energization?authuser=0Test). The WG started its activities on May 2020 and gathers experts of in-situ observations, remote sensing, and numerical simulations. This variety of expertises is fundamental for reaching the science objectives. Indeed, candidates for particle acceleration are shocks driven by eruptive phenomena in the solar corona as the coronal mass ejections (CMEs). Thanks to the joint combination between in-situ (as MAG, SWA, EPD) and remote sensing (EUI, METIS) instruments on board Solar Orbiter and to its vicinity to the Sun, we will have the opportunity to study, with unprecedented precision, the onset of CMEs and the properties of the induced shocks propagating in the interplanetary medium. Thus, parameters as the sonic Mach number, the compression ratio and the shock geometry (both when shocks form in the corona and then propagate in the interplanetary space) will give a quantitative estimation of the shocks evolution and their capability to accelerate particles. Then, the investigation of the phenomena involved in the acceleration and propagation of solar energetic particles (SEPs) that were difficult to resolve from prior observations, will be carried out. Further, being close to the source of acceleration, it will be possible to investigate the properties of the local energetic particle "seed" population. In this abstract we would like to present the ongoing activity of the Italian SWA WG on "Particle Energization", pointing out the physical problems discussed during the last ... |
