太陽高能粒子加速環境之初探

Project Details

Description

Solar energetic particle is one of the major factors responsible for the severespace weather in the solar-terrestrial environment, which can be produced by thesolar flares, CME-driven shocks, interplanetary shocks, and thewaves/turbulences at the trailing edge of corotating interaction region. Thecomprehensive study of solar energetic particles has to resolve the origin,acceleration, and transport problems. In this project, we mainly focus on thepotential accelerators of solar energetic particles, as well as their associations. Inorder to minimize the transport effect in the interplanetary space, we particularlyadopt the energetic particle measurements from the Parker Solar Probe (PSP)near the Sun to characterize the temporal evolutions of intensity and energyspectra. Moreover, the solar wind observations and radio dynamic spectrogramfrom PSP are used to estimate the shock parameters and the related solar radiobursts. By combining with the in-situ measurements around 1 AU by otherspacecraft, we attempt to diagnose the acceleration efficiency of energeticparticles for different types of shocks. We also attempt to clarify the solarexplosions associated with energetic particle events based on the solar imagesfrom multiple wavelengths. This research work covers many significant issues inthe solar-terrestrial environment. Our research results will provide the importantinformation on the warning of severe space weather.
