Le soleil est une étoile active, et les éruptions solaires sont une des manifestations de cette activité. Il est admis que l'énergie disponible pour les éruptions solaires a une origine magnétique, et est transmise au milieu lors de phénomènes de reconnexion magnétique dans la couronne. Une partie de cette énergie permet d'accélérer les particules du milieu (électrons et ions). Cependant, les détails concernant les conditions dans lesquelles les particules sont accélérées et se propagent des régions d'accélération aux sites d'interaction lors des éruptions solaires ne sont pas encore tous compris.Plusieurs modèles d'accélération de particules ont été développés dans le cadre de l'étude des éruptions solaires. Dans certains modèles, les part...
