Particle acceleration and transport in the solar atmosphere
Abstract
During periods of sporadic are activity, the Sun releases energy stored in the magnetic field into the plasma of the solar atmosphere. This is an extremely efficient process, with a large fraction of the magnetic energy going into plasma particles. The solar ares are accompanied by prompt electromagnetic emission virtually over the entire electromagnetic spectrum from gamma-raysdown to radio frequencies. The Sun, through its activity, also plays a driving role in the Sun-Earth system that substantially influences geophysical space. Solar are energetic particles from the Sun are detected in interplanetary space by in-situ measurements making them a vitalcomponent of the single Sun-Earth system. Although a qualitative picture is generally agreed upon, many processes solar are processes are poorly understood. Specifically, the processes of acceleration and propagation of energetic particles interacting on various physical scales remain major challenges in solar physics and basic plasma physics. In the talk, I will review the current understanding of solar flare energetic particles focusing on recent observational progress in the view of Solar Orbiter and Praker Solar Probe.
