Turbulent acceleration in solar flares [PDF]
AbstractTurbulent acceleration in the impulsive phase of solar flares is reviewed, with the emphasis on bulk energization of nonrelativistic electrons and prompt acceleration of the gamma-ray emitting nonrelativistic ions and relativistic electrons. The primary energy release in a flare cannot be due to collisional dissipation.

Jupiter's Auroral Ionosphere: Hybrid Monte Carlo, Auroral Spectrum and Conductivity Modeling
Abstract We present a new model of auroral precipitation and associated phenomena at Jupiter, called the Jupiter Auroral Ionosphere Code (JAIC). The hybrid model follows the primary electron population using a Monte Carlo code that runs on a GPU, and computes the contribution of the secondaries using a two‐stream approximation.

Current sheets in the solar corona : formation, fragmentation and heating
In this thesis we investigate current sheets in the solar corona. The well known 1D model for the tearing mode instability is presented, before progressing to 2D where we introduce a non-uniform resistivity.

A Study of Photospheric Vector Magnetic Field Changes During Solar Flares [PDF]
. Large amounts of energy are released when magnetic field lines reconnect in the corona during solar flares. Observations have found both transient and irreversible changes in the photospheric magnetic fields during flares, but their origins and ...

Solar Energetic Particle Forecasting With Multi‐Task Deep Learning: SEPNET
Abstract Solar energetic particle (SEP) events pose severe threats to spacecraft, astronaut safety, and aviation operations. Accurate SEP forecasting remains a critical challenge in space weather research as a result of their complex origins and highly variable propagation.

Solar Energetic Particle Prediction in the Inner Heliosphere Using Deep Learning and PSP/IS⊙IS Data
Abstract Solar events, such as coronal mass ejections and solar flares, accelerate large numbers of energetic charged particles, producing solar energetic particle (SEP) events that can harm astronauts, damage satellites, and potentially damage infrastructure on Earth.

Ion Acceleration in Solar Flares
Solar flares are among the most energetic and interesting phenomena in the Solar system, releasing up to 1032 ergs of energy on timescales of several tens of seconds to several tens of minutes. Much of this energy is in the form of suprathermal electrons

Solar Latitudinal Distribution of Solar Flares around the Sun and Their Association with Forbush Decreases during the Period of 1986 to 2003 [PDF]
Solar flare events of high importance were utilised to study solar latitudinal frequency distribution of the solar flares in northern and southern hemisphere for the solar cycle 22 to recent solar cycle 23.
