Stochastic acceleration by lower hybrid waves in the solar corona

Abstract

Hot electrons injected during solar flares at the top of coronal loops interact with the cooler chromospheric plasma and excite lower hybrid (LH) instabilty. The saturation electric fields due to LH instability can be of the order of a few hundred V cm−1. Such high electric fields can stochastically accelerate protons and other minor ions. The heavier ions are preferentially accelerated by this stochastic process.
