讲座摘要

Solar flares are among the most explosive and dynamic events in our solar system. They can release massive amounts of energy and accelerate a large number of particles to high energies. As these particles can significantlyimpact our technology and human activities,it is crucial to understand how they are accelerated during solar flares.This task is challenging due to the vast nature of solar flares and complex physics processes (e.g. reconnection, turbulence,and shocks).In recent years,an emerging framework combining theory, numerical modeling,and observations has made significant progress toward understanding particle acceleration during solar flares.n this talk,I will summarize those made by modeling,including kinetic particle-in-cell simulations to study particle acceleration and transport in small-scale magnetic reconnection and macroscopic modeling to investigate large-scale particle acceleration and transport.By combining these results with observations,we have gained important insights into particle acceleration and transport during solar flares.I will also highlight the challenges in understanding complex physics and interpreting modern high-resolution observations using numerical simulations. I will discuss current and future efforts aimed at addressing these challenges.This research area is highly active and exciting,offering numerousopportunities for discovery and impact.
