A little bit of background

Coronal rain is a common phenomenon occurring in active region coronal loops. As the name suggests, it shares many parallels with its terrestrial counterpart; it consists of cool plasma condensations falling from coronal heights towards the solar surface guided by magnetic field lines.… continue to the full article

Introduction

Solar flares accelerate particles that then produce radio emission as they move through the corona. Type III radio bursts are commonly observed signatures of electron beams propagating along magnetic field that extends into interplanetary space.… continue to the full article

85. The role of the magnetic field in sunquakes

Author: Lucie Green, Gherardo Valori, Francesco Zuccarello, Sarah Matthews at MSSL UCL, Sergei Zharkov at University of Hull and Salvo Guglielmino at Università degli Studi di Catania.

Introduction

Sunquakes are sporadic bursts of sound waves that are generated at the surface of the Sun as a side-effect of solar flares and coronal mass ejections.… continue to the full article
